My first SA was Tek 496P, purchased 18 or so years ago for $5300 which was at the time a deal. I sold it in 2005 for $2500 and replaced it with the Instek GSP-810 (breaking even more or less), and as stated in a previous post recently sold the GSP-810 for $1300-meaning that I have a net current expense for the DSA-815 of $300 after eBay, PayPal, and UPS got their cut. My point is that from a performance and overall capability perspective the DSA815 is 2 or 3 (perhaps several) orders of magnitude superior to the 1985 Tek 496P, and at least one order superior to the GSP-810, and cost 1/2 to 1/4 of what its predecessors cost. So here we are discussing 'inaccuracies' of tens and hundreds of Hz, when the best my previous spectrum analyzers could hope to muster were errors in thousands, or even tens of thousands, of Hertz. Short story, I really like this instrument!!!
This is neat. I run a small (8W) neighborhood pirate FM station and do my best to keep the signal from not interfering with commercial stations; and making sure it meets FCC specs just-in-case. Using the DSA815 N dB BW function, and MaxHold, I could easily and accurately record the occupied bandwidth (the FCC spec is 240kHz at -25dB). What I found was that even though my modulation meter said I was kissing 75% I was only occupying 183kHz. A little bit of tweaking my compressor/limiter gained me a bit more punch. I like this little sucka'. I downloaded the UltraSpectrum application (15-day trial) and though I have just played with it a bit I have not yet found anything about it that is worth $260.
To get it to work with the DSA815 you have to edit the UltraSpectrum.ini file it will load into the C: Program Files RIGOL Technologies, Inc Ultra Sigma Instrument Tools folder. The highlighted line shown below must be added to indicate the DSA815 is a supported instrument: I also shortened up the folder and application name that had both been absurdly long; The folder being RIGOLDSA1000AToolsUltraSpectrumV00.01.00.10 With the.exe,.ini and.aliases files being the same with the appropriate extension. Here is what the 'Base' screen looks like: Note that none of the analyzer's settings are populated, I don't know if this is an issue with the '815 or the software. There is an 'Advanced' screen also: I was unable to make anything on the lower panel work, however I must admit I have not read the help file as yet. I was able to compile, debug, and modify their VB6 demo application to talk to the DSA815 via the ethernet connection, adding commands to grab the center and span frequencies, RBW, etc.
I am going to work on reconfiguring my Instek GSP-810 app to work with the '815, should be fairly easy. Here is the trace data retrieved from the instrument, plotted in Excel. I picked this unit up this weekend at the Dayton Hamvention and had an opportunity to spend some time with one of the lead engineers from Rigol China. Great guys, and really enthusiastic about bringing products that 'amateurs' can afford! I wanted to know if you (or anyone) could post a screen shot of your DSA815 while looking at the local broadcast radio spectrum. Mine doesn't show peaks the way I would expect. Unfortunately, I don't see that Rigol has published the sensitivity readings anywhere.
When compared to my friend's IFR 1200S using the same antenna, his monitor clearly shows the FM stations WELL above the noise floor while sitting in his basement. Mine shows barely one peak.
I'm sure his IFR is more sensitive, but I'm surprised. I'm going to try a longer antenna today to see. Also, how long was the wire you attached?
I'm going to do some tests and will post a screen shot later. I am having a ball with mine (also a '815-TG)-far superior to the Instek GSP-810 it replaced, which BTW continues to be sold for more than twice the cost of the DSA815.
For me the TG is an essential component of any spectrum analyzer. I have not yet had the jump drive issue you reported. I thought that perhaps it was similar to my Lecroy Wavejet 322 which computes a checksum for each drive when inserted, which with larger drives (2GB+) can be a mild annoyance-I have a 128MB stick I use with the '322 because of this.
However the capacity issue does not seem to be the case with the '815. I have found that a drive with a large number of folders and files does slow things down a bit-but not as much as you have found. Pulling up the 'drive info' does get very slow with a lot of folders and files. I am still working on my own software but have been slowed down by a client that decided to update their 50 workstations from XP to Win 7 by themselves. 'To save money' they told me-guess what isn't going to work out as planned?
It is happy with that stick if it is inserted while the SA powers up so I can't see it being upset by the format or contents. I tried some more, the SA locks up when the stick is inserted. Sometimes it detected the stick after about 30 seconds, one time I gave up waiting after 6 minutes. Another stick I have is reliably detected in 2-3 seconds.

The stick it doesn't like is a Kingston micro-SD reader, however, it is happy with the same micro-SD card plugged into a dirt cheap no name SD card reader. I have been able to duplicate what you report, using a cheap Twin-MOS '8-in-1' (I never have figured out what the '8' are?) card reader, and SD cards none of which worked at all even after waiting several minutes. However the same '8-in-1' thingy worked fine with the various CF cards I have accumulated.
All of the dozen or so USB jump drives I have work fine. I had a somewhat similar problem with a Lecroy 9354L 'scope that had a PCMCIA card slot requiring SRAM. It worked fine with the older SRAM cards having replaceable backup batteries, however it froze when an SRAM card having a rechargeable non-replaceable batteries was inserted. Yet when the rechargeables was inserted before powering up the 'scope it worked fine. What I found was that the initial +5V current draw of the rechargeable cards was pulling the 'scopes +5V bus low enough to glitch the instrument's microcontroller. Oddly the rechargeable cards worked fine with the older Lecroy 9400 series 'scopes. I have been able to duplicate what you report, using a cheap Twin-MOS '8-in-1' (I never have figured out what the '8' are?) card reader, and SD cards none of which worked at all even after waiting several minutes.

As an educational experience I tried RunAsDate (RaD)-aren't NirSoft's utilities amazing?-however the EXE cannot be launched independently of Ultra Sigma (USig), it pops up a dialog stating so. When installed it creates an Ultra Spectrum.ini file in the C: RIGOL Techologies, Inc Instrument Tools folder, and USig launches it from a FQPN specified in the Ultra Spectrum.ini file ( ToolsSetupPath).
I added RunAsDate (with appropriate parameters) to the FQPN in the.ini file however Ultra Sigma then did not even show Ultra Spectrum (USpc) as an available tool on the Tools drop down menu. I even, again as an educational exercise, wrapped RaD and USpc into a VBScript, compiled to an EXE named the same as the original USpc executable. This time it appeared on the USig Tools menu. The compiled script launched, then launched Ultra Spectrum which complained it could not find the instrument (TCPIP connected in my case, I suspect Ultra Sigma establishes the socket provides it to Ultra Spectrum). If I felt there were some overwhelming need for me to utilise such an underwhelming application ( Ultra Spectrum) I might have gone further, however as my re-written GSP-810 application will do all that USpc does-and whatever I might like to do in the future-the point of diminishing returns has been passed.
I did after creating an account at the customer center. Two days later no response, not even and acknowledgement that I posted a question.
I also mentioned a nasty DSA-815(-TG) bug. Hook up the TG to the input. Set full span, set the attenuator to 0db and pre-amp on. Set the TG to 0db. Set the sweep time to something long, say 1000 seconds. Turn on the TG and now your analyser is locked up for 1000 seconds. It responds to nothing but the power button and if you have it set to restore the power off settings it will lock up again as soon as you power on.
To regain control remove the input signal and when you turn off the TG you will get one 'IF signal out of range' warning message presumably referring to the continuous overload which locked up the analyser. This seems not to be TG specific. If you set zero span and put in a constant signal at the centre frequency it also locks up beeping at you, sometimes with and sometimes without showing the 'IF signal out of range' warning. Smells like a constant IF overload tries to show a zillion 'IF signal out of range' warnings which locks up the UI without managing to show one of them or beep if the TG is on.
There is 1.05 firmware which is supposed to improve demodulation. I was emailed it indirectly from Rigol in Germany after approaching Batronix where the SA came from. Could someone confirm or deny this bug.

Apply a -10dbm signal frequency doesn't really matter (10MHz). Turn on the pre-amp and press Auto. When it has found the signal reduce the input attenuator till it starts beeping and showing IF signal out of range messages.
Then set zero span. My experience is the analyzer will stop updating the trace, beep continuously and not respond to any key except the power on/off button. It is another version of the problem with the TG providing a continuous mixer overload locking up the UI. You need to remove the input signal to recover. I also mentioned a nasty DSA-815(-TG) bug. Hook up the TG to the input.

A few weeks ago it came to our attention that Rigol’s DS2000-series oscilloscopes were. We had expected a small microcontroller device would be developed to send these bits to a scope automatically, and we never imagined the final version of this tool hack would be so elegant. Now it’s possible to and a great encryption hack.
The engineers over a Rigol (bless their hearts) used the same hardware for the $800, 70MHz DS2072 and the $1600, 200MHz DS2202. The only difference between the two are a few bits in the scope’s memory that are easily unlocked if you have the right key. A few folks over on the EEV Blog forum figured out the private key for the scope’s encryption and the user. The upgrade process is extremely simple: get the serial number of your DS2072, put it in the keygen, and enter the resulting key into the scope. Reboot, and you have a $1600 scope you bought for half price. Posted in Tagged, Post navigation. I tink you’ll do better in business getting more for your money.
What is NOT good business is taking advantage of your customer. If I had paid $1600 for a unit that was the exact same as a $800 unit (and cost the exact same to produce), I would be very angry. As a customer, you have to assume that if one model costs double what the other does, that there is some higher cost to drive that price. In this case there isn’tthey just locked up some capability to extort more money from the guy who is willing to pay more? Why don’t they just charge $800 for all the units and not have the capabilities locked up?
I guess because some people are willing to pay more. That’s all fine and goodunless you’re found out, as this company has been. If there’s a reason to charge more money for the higher end unit (like it uses better components, or has other costs that are higher), that’s one thingand that’s expected. But if they are truly the same unit and just locked up, with one person being charged double, that seems unethical to me.
If not unethical, then risky. Nothing stays a secret for long. They’re not taking advantage of their customer, plain and simple. You might have read what I wrote, but you missed the point of it. Pay $1600 for a unit and it is.not. the exact same as the $800 unit it’s got better capabilities and functions. Pay $800 and get the unit with lesser capabilities and functions, but if it’s the unit you need, then it’s the right one for you.
If you need the better capabilities and functions, then pay for them. “Why don’t they just charge $800 for all the units and not have the capabilities locked up?” Really?
Good luck with that. If they were going to standardize on price, they’d set it at the higher price, a price which is competitive for the feature sets that would be available.
What you (and everyone else here who’s whining about it) fail to get is that they’re doing us a favor by making a downline unit available at an excellent price that more than meets the needs that most of us here have. If any of us need more bandwidth, then there are upline units for that with commensurate pricing. If you ever get around to living in the real world, you’re in for some cruel surprises! The market provides the solution if you don’t like it, do it better yourself. “If I had paid $1600 for a unit that was the exact same as a $800 unit (and cost the exact same to produce), I would be very angry. As a customer, you have to assume that if one model costs double what the other does, that there is some higher cost to drive that price.” So your assumption is that everyone is selling you their products based on the cost of the transistors and resistors?
Or maybe it should be based on the cost of the raw carbon and silicon? Prices for anything you buy are set based on supply and demand. Lowering the prices means generally (not always) you will sell more units. If the profit from those extra units is sufficient, it will offset the price decrease. Thus, there is some optimum price which results in the most profit which is neither the highest nor lowest possible price.
However, this means some people who would buy your product at a lower (still profitable) price don’t get to. It would be better if you could make special discounts for them, so they can still buy it, but without cutting out your existing profit. The way to do this is price discriminations. This is why coupons exist: to the poor people who are making minimum wage, it’s worth it to cut out newspaper adds and get the best deal. Wealthier people making $100 an hour will not spend an hour searching for deals to save $10.
Now, if this company selling the oscilloscope was not able to sell $800 and $1600 versions, instead what you would be looking at is one unit marked at (say) $1200. Great if you were going to buy the more expensive $1600 version. But really sucks if you were going to buy the $800.
And, of course, it’s the poorer people who are losing out. So I am totally a fan of price discrimination. It’s not unethical, it’s to your benefit, at least if you’re strapped for cash like I usually am. That said, I also don’t see anything wrong with modifying hardware you paid for in any way you please.
And the company probably doesn’t care — few, if any, of the people ordering $1600 units are going to order the $800 units and mod them. Saving $400 is nothing to them, but a multimillion dollar lawsuit for breaking the license agreement, or even just the cost of no longer having their product officially supported, might be. And the company may indeed wind with more sales from a new price discriminated bracked, e.g., people to whom the $1600 machine is only worth $1000 but are willing to mod it can now buy it for $800 when they would not have bought either unit before. If I had paid $1600 for a unit that was the exact same as a $800 unit (and cost the exact same to produce) Precisely. Typically the arguments for increasing pricing structures have been that you have to pay more for people to work more. You pay more for better things because people put more work into it, or the raw components are higher quality and cost more, etc. In this case none of these are true.
Both units are exactly the same, even the software is the same. The only thing different is the manufacturer PUT MORE EFFORT INTO THE CHEAPER UNIT TO CRIPPLE IT. So with all that extra work they could charge less for it? That already doesn’t fit into their typical production model, so you have to question why it’s suddenly convenient.
This is a really cynical, corporatist thing. The only true difference between these 2 units is the sticker on the front. If you want to be a sucker and pay $800 for a different sticker then you do that, leave the rest of us out of your ‘ethical dilemma’. It’s different in the case of processors; by necessity you need to print multiple processors per chip because you’re very likely to get an error on any single processor. In that case, you actually end up needing to turn off your backups because the rest of the chip is only designed to operate X number of cores at maximum.
Also, companies do this because it would not be practical to have two unique production lines. I’m not sure about an $800 difference on a scope like that, though.
It does seem they could price the product at 1K and not mess with it at all. It’s a door in a house that was sold in two versions, 2 rooms and 1 room, and you went with the 1 room one, which was sold at a fair price that you were happy to pay, plus the 2 rooms one you couldn’t afford anyway.
Now you realize the house does have two rooms, you get it unlocked by the locksmith and complain that you got ripped off because the seller should have given you the fully unlocked house for the price of a single room house. The fact that pricing can include things such as development cost or any number of factors, not just the price of components making up the product seems to be lost on many here. Not saying that you should not hack the scope, I would probably too, but being pissed off at the company is just narrowmindedly naive. @Nelson: I certainly don’t agree that such a system is anywhere near ideal, but that’s what we’ve got, no? Such license agreements include a clause giving you the option of returning the purchase if you disagree with that license, so there’s something to be said for reading the manual. If the company constructs their EULA in a way that runs afoul of the law, then the courts have final say.
But this is all largely hypothetical, as it’s up to the party that has been wronged (the company) to choose whether or not to try to seek damages. Ultimately though, whether a company does or doesn’t try to seek damages, the ultimate question is whether or not such a hack is ethical. Becuase it boils down to theft (there was a mechanism in place to prevent access, the method was circumvented, a benefit above that which was paid for was gained, the company wasn’t compensated), on the ethical question, such a hack fails. That’s not to say that I don’t have respect for the mad skills of those who devised the crack, and it’s certainly not to say that I don’t have less respect for the company for not protecting their IP very well (whoopsie!), and it’s not even to say that I don’t think that in many cases, this crack will be harmless (as others have fervently pointed out, it’s not like many of the folks that will do this were ever going to pay for the better feature set). But it is to say that such cracking certainly falls short of being ethical.
That was the topic in question, that is the clear conclusion. All the comments I read here miss the point entirely. Rigol could easily fix this. In several ways. Especially after they had it happen on previous scope models like the ds1052 series.
They purposely leave in the backdoor to sell more units. It brings them TONS and TONS of free advertising(like this thread) and people would rather buy the $800 scope and feel like they are getting the $1600 scope. I am sure having a method of hacking the scope they end up selling 2x the units. They will still sell lots of $1600 units to companies etc that don’t want to mess around with warranties so they really have very minimal losses as anyone who needs the capabilities of the $1600 version to make a living will pay for them and not risk having their scope downgraded by a future fix. As far is the question of it being ethical. Of course not they want you to do it otherwise you might go with a different brand etc.
The concern brought up here every time one of these articles is posted and never (to my knowledge) given a conclusive answer is: will it perform to the right level? If the part failed testing at 200MHz and was therefore put into a 70MHz scope, then you can unlock it all you want, but it still won’t hit the performance you’re looking for. Is the filtering set up the same?
Anti-aliasing is probably going to look quite different between the scopes. Maybe some of the other parts are lower grade as well because they can get away with it. It is a common technique to keep the hardware setup the same between products that come in different flavours (performance/features) and just lock/unlock those using software/keys. This is done to save costs for production/storage/hardware-development on products where the cost for the actual parts is low in relation to the sales-price. I would guess a scope falls into this category. Since an option to upgrade the scope via a key was made available to the user I guess one can also buy that key from Rigol to upgrade the scope. Soft(firm)ware controls are just straight up foolish on the part of manufacturers.
If I’m going to build a device like this, I’m going to build in a physical reason why you can’t just flash it and get all the goodies. I don’t see any automobiles out there that can be software fiddled from a Pinto to a Mustang,or even a base level Mustang to a fully loaded one It’s going to have to be better than an extra resistor or a bridge somewhere that somebody with the right tools can just desolder and free the thing (I’m thinking about opening up forbidden bands on ham radios here); you’re going to need to buy a physical part from me. Or a different unit. It’s inefficient and counter-intuitive to our network enabled minds, but if I want people to pay for a premium product, I have to have a serious means to control the premium.
I applaud the sorts of measures highlighted here; there isn’t really much of a reason why one should pay an extra $800 other than because the manufacturer can get away with it. If they can’t get away with it, then the price for the better unit will come down to reflect the realities of the manufacturing process (slightly better components, a bit more testing time) and not just a profit grab. It’s not exactly like that. Firstly, paying for software features is a pretty common thing. There is plenty of software where all the features are bundled in and their use is controlled on the basis of the license you’ve purchased. Secondly, it sounds crazy, but people have related stories here and to me in person (unrelated to each other, but very similar stories) where they were basically required to take the more expensive option out of the available choices for business reasons rather than practical ones. Thirdly, if you think of it as them changing a line of code and offering it to hobbyists for half the price, it doesn’t sound quite so bad now does it?;).
It is very apparent who has engineering experience on a high volume production device and who is a hobbyist. One of the major reasons the scope is so cheap to begin with is due to their high volume design decisions. One piece of hardware with firmware cripples is an enormous cost saver in terms of inventory management, configuration management, volume discounts on parts, and countless other issues involved in dealing with multiple hardware configurations and software/firmware to support all of them. Sure, they could hardware lock their scopes, but they didn’t. They saved a lot of money in doing so and that possibly allowed the scope to be affordable to you.
If you cant see beyond the scope of just a hardware device and look into everything that goes into a product, it isn’t a big deal, as long as you understand that a LOT more goes into engineering something than just making the physical device. Making a keygen to steal IP from something you didn’t pay for is wrong and it doesn’t matter how you spin it. So what you’re saying is that the reason we can have the “lesser” scope for $800 instead of (say, $1500) is because they built more or less identical units and did a soft lock instead of tooling up another line and building a different unit? That suggests that the true value (which reflects the costs to the manufacturer, of course) of the units is represented closer to the higher rather than the lower price? They’re then doing us the market a favour by selling below profitable levels? Or, perhaps, the “real” value of the full scope is closer to $800 (and profit must be made by the manufacturer somewhere less than that, since middlemen want a cut too) and they mark it up to take advantage of an artificial difference?
I want it to be the first, but I’m suspicious. I don’t care about stealing IP for the purposes of this discussion, that’s a different matter. The first important lesson you learn is that there is no inherent value in anything. The value of an item is exactly the amount people are willing to pay for it. Businesses don’t mind dropping $1500 on a scope that they know will meet their requirements.
They can’t sell many of those units to hobbyists though, so they put a unit up at $800. They need to differentiate it so they lock out a few features that they judge the hobbyist won’t need (but that higher-end users probably will). End result – they have a range of units that they can sell to different market segments. What you’re saying is finebut what it sounds like is “this guy will pay more, so let’s grab him for more, and the hobbyist can’t afford all this, so we’ll sell him one that’s cheaper”. But if all the costs are the same for both unitsis that a smart thing to do? The risk is that your unit will end up on hackaday.com and your customers will find out that they seemingly overpaid.
You’ll loose customers. And they’ll be the best customers too.the ones that pay $1600 for a $800 piece of equipment;) I think that if a company is trying to sell a unit for a lot more than a seemingly identical unit, they’re taking a big risk. Especially because in this situation, the hardware is there. The cost is already paid by the manufacturer. They’re just locking it up and preventing the customer from using it, at no extra cost to them.
“The risk is that your unit will end up on hackaday.com and your customers will find out that they seemingly overpaid. You’ll loose customers. And they’ll be the best customers too.the ones that pay $1600 for a $800 piece of equipment” Except they didn’t, they paid $1600 for the features to be available and supported by the company. As hackers it’s easy to forget that these official support channels exist if you’re willing to throw money at them. If something doesn’t work, we go online, we look for solutions, and we have a go at fixing or improving it. If a company buys a product and it doesn’t work, they file a ticket with the manufacturer’s support team. That extra $800 is effectively guaranteeing that support is available and the unit is correctly specced to provide the features you’re using (remember that parts could be in the lower spec scope for the exact reason that they failed testing at the higher spec).
The first is essentially what it boils down to, yes. They could make 10 unique models with tooling and R&D costs for each, and charge a large sum for any of them until X number of units were sold, they’d recouped their costs, and they could afford to lower the prices. But by making a shared platform and differentiating in software, they’re essentially passing along the savings in advance, without having to wait and see if certain models are going to sell enough to allow for the price to come down. This business model is evolutionary and efficient. Its weakness comes from what we’re seeing unfolding here without sufficiently protected software, the product can be exploited. Granted, the market is sympathetic in that additional units are sold in order for more people to be able to use the exploit,.but. all the cost projections and etc that went into the initial project get thrown off, and costs don’t get recouped as hoped.
The reflexive solution to this is to raise the price to compensate for lost sales, and this ends up penalizing later adopters for the sins of the initial exploiters. The circle goes round and round, but ultimately, there’s a financial penalty that becomes expensive in and of itself to recoup. As a result, future costs of all models go up faster than they otherwise would have.if everyone had played fairly in the freaking first place.
Moral: Everyone loses when someone cheats. @Kemp: Nobody said anything about inherent value, but there is a price point where the product isn’t profitable, which is what I meant by “true value”. Value isn’t the right word to be using, of course.
@Rob: Fair enough, but the business model does not sound evolutionary or efficient at all, those words smack of economic warm-fuzzy buzzwordery. It sounds daft for exactly the reason we’re talking about this, and comes back around to my initial point; Software locks are demonstrated useless at keeping people out time and time again. But businesses keep using them! And people keep breaking them! And then we get the boring moaning and chatter about IP and ethics and so on. The cold, hard truth is that if you don’t want people breaking into devices and unlocking them, you don’t lock them in the first place.
You physically remove functionality. Doesn’t matter if it’s “inefficient” or right or just or whatever, you want to keep people out, you put it somewhere they can’t get at it until they’ve paid for it.
You get no sympathy from me for me for trying to use a system (soft/firmware locking) that has been a repeated security failure. I fully agree with Skimo and his comment already contains the answer to yours: There are different sorts of costs related to a product. One is a recurring cost that has to be spend on every product manufactured (parts, manufacturing, testing, shipping, margins for resellers and so on). If the sales-price is above the sum of all that you are not making a loss by selling a product. However – there are also initial costs that happen when you develop the product (research, development of hard- and software, other stuff like compliance testing, certificates depending on the type of product, marketing) and you want to cover those over a certain time when your product is sold.
If you have a product that can be sold with different performances (let’s just say a cheaper entry-level version and one singing-and-dancing one) you will price it that you make a profit on each – but the profit-margin will be higher on the more expensive one (obviously). However – depending on your market (and that research you did to find out about it) you will sell a lot more of the cheaper version because it fulfills most peoples needs. If you would not offer that cheaper version many of your customers would buy a different product because the high-end one is too expensive for them. Which means all the initial costs for the development would have to be covered by the expensive version – making it even more expensive. To sum it up: No – the manufacturer is not doing the market a favour.
He is spreading his costs among different groups of customers allowing himself to access to those potential customers. The alternative would be to develop a product somewhere in the middle – which may still be too expensive for some customers and not good enough for others. I agree, ultimately this is more to do with people choosing to hack their device, voiding the warranty to unlock features they in fact did pay for with their original purchase price. You can’t turn around and make customers unhack their device, this is a breach of both the Constitution (freedom of choice) and Human Rights.
The only real issue is whether someone can then sell the ‘scope thus modified as a more expensive product and get away with charging a higher price. It is a bit like buying a phone, finding out that it has a hidden FM radio SDR chip and making a wideband spectrum analyser with it. (Disclaimer: Some Android phones have such a chip, used as part of the phone chipset to work in 4G mode so enabling this feature may break 4G.). One point my boss points out everytime I tell him about these hacks is the bandwidth of the probes. See all 201 rows on serialnumber.in.
Sure this doesnt apply to the firmware features (like serial decode, or memory depth). I doubt they are selling the “low-end” scope at a loss, but I’d be surprised it they would have made back all the investment (tooling + man hours on firmware) if the didnt offer the higher end model. Saying that, I dont think hobbyists would foot the bill for the higher end model anyway – so its the movie production/studio argument against piracy (1 million people pirated a film, so thats lost revenue). Piracy here is a delicate topic.
Yes, I see that both the expensive and the cheap scope cost probably less than if they had developed two different scopes with different hardware. But the question is what you lose due to such a hack as a manufacturer. Would you have sold the expensive scope otherwise? Would you have even sold the cheaper one to the hobbyist, or did he only buy it because it’s such a steal after the hack? Business customers will likely not hack their hardware this way.
Saving a pittance on a scope for the risk of running it outside its spec and ruining an expensive project? Not worth it. Unless it’s a really small shop that probably couldn’t afford the pricier unit in the first place and needs to cling to every penny.
The possibility to apply piracy to the device could be a net win for the manufacturer. Whether it is or not in fact is moot to discuss. Personally, I’d really like to see the same kind of thing for hardware that exists for software already: different prices for hobbyists and professionals. It’s just an extension of the idea to up the scale of production through selling the same unit with and without limitations. I see, though, that this would be very hard in practice and probably just end cannibalizing the commercial sales. I btw do write software for a living. If any of that could have the slightest use for someone to use privately, I’d license it for cheap when restricted to non business use.
If any individual would pirate my stuff to use it without making money, I wouldn’t care. There’s simply no one who would pay several grand for what I make just to use it at home. If I’d see a business using it unlicensed, though, they’d either have to pay or would get sued. Distributing software costs practically nothing, yet it is priced like goods where you have fixed costs per unit. It should be priced according to its use for the customer.
There is also a hidden profit for rigol here. They where relatively unknown until people released the 100Mhz hack for theyr older model, now every hobbyist looking for a scope knows them, heck the demand for the cheaper model was so great that they were able to lower the cost of the factory unlocked one and that is the one i got as i didn’t want to loose the warranty, for the ones that did unlock theyr scopes rigol also made some extra profit in the guise of less returned broken units has any good manufacturer also takes into account the probable cost of warranty claims.
Now they have another round at it and if they price their new model right they can nail the market with their 2nd generation hobby scopes that really are just cheap (in price) pro scopes (save some “the probe costs more than some labs” niche market). Probably not any more unethical than purchasing a Windows computer & removing Window to install Linux or any other OS.
I guess it comes down to if you need or your clients expect instruments with guaranteed performance at 200 MHz to be used. In the event this would void the warranty is something to consider, if the unit ever needs to be serviced by Rigol. You scoff at warranties & proudly void them? I’m not sure if spending $800 with modification in mind to to save $800, if the unit ever needs to repairs that only Rigol can do within the warranty period, a gamble only the purchaser can decide is worth to gamble. Of course if one already owns a DS2072 no longer covered by the warranty, the warranty is no longer a concern.
This is spectacularly smart marketing on Rigol’s part. Higher performance scopes are mainly bought by corporate/academic labs. So if they can expand the market for their low end market by leaving it hackable, knowing that the hobbyist choice is between hackable Rigol and unhackable competitors, why not? The average person who buys a Rigol because it’s hackable will never get around to it because (s)he actually doesn’t need the higher-end performance. But this certainly gets Rigol free publicity and mindshare. Look at the number of people arguing about this.
What percentage of users will actually apply the hacks? The choice by the invididual end user isn’t generally between buying Rigol A v Rigol B, it’s whether to buy Rigol or Tek or Agilent or generic Asian brand.
This might be a clever strategy on Rigol’s part too. They surely must know about the hack of the earlier models, yet the new model is still easy to crack.
I expect more people will buy from Rigol because they can hack it. Rigol gets more sales and more money as a result. How is that bad for them? I think I would rather have someone buy my product regardless of what they were doing with it, than buying someone else’s. They would still sell the higher end model to those who want a guarantee it can do what it says on the label. There is no guarantee the hacked low-end model is accurate when unlocked. While it’s actual “piracy” the effect is a net win for Rigol.
Most of the people who will do this hack are hobbyists, meaning that they will sell more of the bottom line scope (sales who might go otherwise to another vendor = win) for this market, a market where the actual amount of sales for the high end model will be rather limited anyway. I cannot see any decent lab/prod env using this “hack” besides maybe on one off basis on a surplus scope for “fiddeling around”, in any production env the actual thing that matters is calibration and vendor confirmed specs, the hack may be working 100% the simple fact it’s not certified by the vendor alone means it’s a no-go for critical applications, hence they will buy the unhacked full version anyway.

Hence the actual loss of the high end level should be very limited and counter balanced by the surge in low end sales and the actual exposure (= free advertising ) of the model line due to all the attention it draws. And there’s the rub. Only a couple posts have brought it up, but it bears repeating.
Results aren’t guaranteed. Heck, with production irregularities, some of the downgraded/now upgraded scops might be more or less accurate than others you’d have to test every single one to know for sure. And to do that you’d need standards. And if you had ready access to standards (in most cases), you’d have had sufficient funds to just purchase the better model from the factory in the first place with the understanding that you could trust it and wouldn’t need standards! What I want to see are the service menus on these units where do you go to make adjustments if you’re trying to calibrate it?
Are the calibration values built in (since it is a digital scope after all)? This is the tip of the iceberg. “You don’t have to sign it for it to be binding. Your acceptance of the scope is your agreement” That is BS. The Bill of Exchanges Act of Canada (or equivalent in your country) should be consulted. If the contract was not signed BEFORE the acceptance of paymeht, tough bananas. Any software company trying to impose an EULA is nothing more than bullying, and doing false representation.
If they claim that their EULA holds, then, they also must expect that some people will not want to agree with the EULA, and then, they expect them to spend time and gas to get the stuff back and get a refund. Well, this is use of my time, and for that kind of activity, if they imply that there can be tacit agreement, it means that they agree to my terms implicitely. My terms are that any software I have to bring back to the place of purchase and get a refund for because I was not properly legally notified about it will be billed at 100,000$/hours, plus 2547$/km to get back to the refund point. Too bad (for them) they did not have a proper contract signed at the point of sale, isn’t it? Once the transaction is concluded, once money was exchanged, absent the explicit and LAWFUL (not “legal”) contract, their claim is utter BS.
- Using a Rigol product key to generate a Rigol software licence code. Last Updated: The Rigol software licence code generator can be found here. You must enter the product key exactly as it appears on the certificate. The serial number is made up of capital letters and numbers only - There are no lower case letters and no spaces. Please take care when entering the serial number!
If you enter an incorrect but valid serial number, the generated software licence code will not be accepted by your instrument. You might find that entering the software licence code into your instrument via the front-panel is rather tedious. Please note that it is possible to enter the code remotely from a PC, using the SCPI control panel within Ultra Sigma.
Copying the software licence code from the webpage generator to Ultra Sigma reduces the risk of error. For further information, please refer to the Ultra Sigma Help Document and the Programming Guide for your instrument. Both of these documents and the Ultra Sigma software download can be found on the webpage for your instrument, under the ' DOCUMENTS, SOFTWARE & VIDEOS' tab. For some models it is possible to download the generated software licence code as a '.lic' file, save it to a USB memory stick, then import it into your Rigol instrument from the USB memory stick.
