content: I just acquired an Agilent DSO81204A scope that had a bad power supply (now fixed), and a hard drive that was full of specialty software apps from the previous owner that interacted with the Infiniium scope app and managed to slow the scope to a crawl. According to the serial number tag, the scope originally came with factory installed options 001 (expanded memory) and 003 (serial analysis and mask testing).I decided that the best way to get the scope to a known good state was a full restore from the hidden restore partition on the hard drive. The restore went well EXCEPT that the two options were no longer activated. I don't have the license keys for them, and Keysight can't seem to locate them either.What's the best way to get these options reactivated? I really like this scope, and the expanded memory would be very helpful (and I wouldn't mind having the serial analysis and mask testing options either)!Thanks,Stan

content: Ouch, the proper thing to do was to copy off the license files before restoring the scope.

content: QuoteI would have expected that Keysight would be able to regenerate your option keys based on your model and serial number.Do you know the full serial number of the scope? If so what is it?QuoteI think the licence file will be (was) in a hidden folder so to find it I think you have to alter the folder options to allow them to be viewed and copied. But I guess it's too late now.But post up the serial number anyway if that is OK.

content: s/n MY44000238The service manual said the scope would be restored to its original condition, so I assumed that since the options were factory installed they would survive a hard drive restore. Guess they don't!Anyway, all is fine now. A Keysight engineer told me that I might find a factory label on the back of the scope with the license keys and indeed I did. Thank goodness the label survived the hard drive restore!On a related note, since this scope is well out of support by Keysight, is there any way to enable more of the options?

content: That was a lucky breakDid you have to type in a (12 digit?) key for each option?If so, can you post up one of the 12 digit keys? It will only work on your scope so I guess it's OK to do this. Just one key would be interesting to see and you don't have to say which option it enables.

content: Not really... those were the numbers I was expecting to see.I managed to write licence files for a DSO80404B a while back and converted it from a 4GHz scope to 12GHz and this was proved with a >12GHz sig gen. But I didn't do it via the GUI keypad system. I bypassed the GUI and just wrote the raw licence file instead. So maybe this is why I can't make sense of your front panel nnn-nnnnnnnnnnnn numbers.There is a dat file and I recall that it is in the (hidden) scope\bin folder but I think I know what text it will contain. This file gets created after you type in your keycode. But I did all this a year or so ago and I only had access to the scope for a short time.

The only difference between each of the lines (other than the actual key) is the descriptor. I wonder how critical it is to have the exact descriptor in the license file? Maybe trying a few well-reasoned guesses (e.g., "noise" or "bandwidth")?

content: I really need a bit of time to work out how the system works. You can see from your dat file that I was trying for ezjit yet it appears to unlock ezjit plus instead? The 12 digit code is a bit like an compressed/encrypted recipe for a cake and it can be unravelled to describe the ingredients that include the option, the scope model and S/N and expiry date etc etc.Note that I'm fishing around inside a huge windows PE file to decrypt this stuff and their code is riddled with options. Some look to be hidden options and last year when I unlocked 'everything' on the 80404B scope, the list of enabled options was so long it was way, way too long for the options window on the scope display to cope with. But I don't know how many of them were actually valid for that scope model. Also there appears to be various ways to describe each option and it could be that you have to get the correct descriptor for a certain model.There are dozens of bandwidth related descriptors in their options code so your best hope is to find someone who already has option 005 and report back?

I will ask around and see if anyone has an Option 005 scope who might be willing to share the particulars, including the license.dat file. In the meantime, I am VERY thankful to you for all of the help you've given me on this. I'm starting to understand the process a bit better now, but I clearly have a long way to go to get anywhere close to your level!

content: I did some digging in the code and found a noise only option and this may be option 005?edit: probably best to wait until you can prove this is the right option for your model number, but it appears to use noise as the feature. But I can't be certain.I'm still struggling a bit but I did also manage to finally replicate your original factory codes on the back of your scope. So some things are making more sense. The other option I found was the low speed serial option for SPI and I2C etc. Do you already have this included in the high speed option?

timestamp: January 28, 2018, 01:29:33 am
content: Sounds like you're making good progress! I didn't see an option for low speed serial in the options list I got from Agilent/Keysight. Right now the scope is down while I clone the hard drive to an SSD, but once it's all put back together I'll let you know if the high-speed also does low-speed (I assume it would, but might as well make sure). Thanks!

content: Turns out that low speed serial data analysis for I2C and SPI requires a separate license (option 021, or N5391A). Reading between the lines, there may also be another license for FlexRay and CAN (N5402A). Does this fit with what you've found?

content: OK that's good. I'm nervous/reluctant to explore the memory or bandwidth or noise options because there are so many of them and it might confuse or even damage your scope if I unlock an incompatible option. There also seem to be options for pretty much every type of interface found on a PC motherboard or network or graphics card and plenty of other stuff I don't recognise. But some of it probably won't be for your scope so it could cause problems. Also, I don't know the correct three digit code for any of these options unless it's obvious (and safe) like the LSS code for low speed serial. I did check the datasheet and your scope does support the LSS option so I did expect it to work OK

content: I appreciate your concern. I'm curious, though, how a software option could damage the scope's hardware (I presume that's what you meant). If one of the codes were to cause a problem, wouldn't the software just object to it somehow, and then it would just be a matter of restoring the license file to its previous state?I agree that there are lots more options available for this scope, but there are only three that would be of any use to me: InfiniiScan, Noise Reduction, and Increased Bandwidth (in that order).To reiterate, I am extremely grateful for all the help you've given me so far, and I understand your reluctance to generate potentially hazardous codes. But having said that, if you ever do want to generate more codes I'll be willing to assume any and all risks and give them a try!

content: You should be able to get all the codes from Keysight (based on the scope serial number) assuming they keep reliable records. I don't think it's a good idea for me to generate your codes for various reasons so your best bet is to contact Keysight.Note that I think the 8960x SW uses the 21x4 SIGN system in FLEXLM and this is more secure. The version of the 8960x SW I have here uses this system so I assume they all do. That doesn't mean it isn't possible to create DIY .lic or .dat files for it but it is a tougher system. When digging inside their code I found there are extra (hidden) options within the 8960x SW that can be released with a suitable feature entry in a custom .lic file. I've done this and got these options but I never experimented with them to see what they do. They aren't documented anywhere by Keysight. I think I found about 10 hidden options but I can't remember now. I did all this stuff a few years ago now when I bought an old E4406A VSA to use with this SW.

I mean it's not that Keysight would lose any business.I don't care for this VSA software whatever it does but I'd really like to get the other options back.

This is pretty disappointing.So if a device is obsolete, is it no longer supported in any way?I expected better from Keysight.Maybe it would be helpful to contact David from Keysight (Keysight_DanielBogdanoff here on the forum) directly. He sometimes makes the impossible possible and he is a real win for Keysight, as he adds a lot to Keysights reputation here on the forum.

content: I have *copies* of the invoices for the options which are so bad they are barely readable (propably copies of copies of copies, with scribblings and cut off heading, probably because someone wanted just the option list on it). And Keysight said they wouldn't have needed them anyways but for these obsolete scopes they can no longer get or generate option keys.They were really nice and apologetic, but they said there's nothing they could do (one even went back to ask in the relevant department).And I can't blame them, it's an obsolete scope after all.Not sure what you expect, really, obsolete means obsolete for a reason. You can't expect them to keep software and databases of obsolete products around forever because if they do it still costs them money. And for what, a few hobby buyers who aren't their customer in the first place?They could have published a last update enabling all options, but then which manufacturer would do that?

content: Hi all,Reviving this old thread. I was working on an DSO81304B that had issues with the internal LVDS display card. I thought it was fixed, but it kept having software issues and causing the scope app to crash randomly on startup.I changed some graphics settings and Infinium was able to launch normally, but it crashed on shutdown. The unit lost the license keys from what I can tell, as they have disappeared in the software.I tried re-entering some of the keys that are on the rear panel label, but I get the error message "License installation failed. Please contact Agilent technical support".The model # is DSO81304BSerial # is MY46001306Option ID number: 304BThe serial tag says options 001, 007, 009 were ordered with it. There were also a few more purchased afterwards by the original owner, as you will see in the license.dat.bak file contents:QuoteThe sticker on the back has a few keys; I tried entering each of them carefully, and got the same "installation failed" message.Attached a few relevant pictures as well.Is the "License installation failed.

content: Also, not sure if there is some kind of memory that was corrupted by the display driver crashing the scope app on exit.I tried installing the latest compatible Agilent IO libraries suite, and removed/reinstalled the 5.71 scope app. I made sure license.dat.bak and any files named "license" were deleted before install.When the scope rebooted, it popped up with the same 3 options it is stuck on now:Enhanced bandwidth, Low noise, Ext ref clk.I tried copy pasting a copy of the original license files into the scope/bin folder. No changes.Does anyone know if there is some flash on the acq board or PCI scope interface card where the option config is also stored? My guess would be that this memory could be corrupt and needs to be reflashed with a good image.I try to run the Infinnium scope app without the pci card installed, or with the front panel/acq board ribbon cables removed, but the app wont launch to splash screen so I can see if it loads options or not.I see that G0HZU was able to run the Infiniium app from an emulator, not on actual scope hardware. How is that possible if the app requires the scope hardware to even begin launching?

content: Thought I might share a pretty picture.While I was browsing around for other flash memory on the scope I was able to discover a few things:Scope app will run with front panel board completely disconnected, so I'm sure there is no config flash on thereScope app will not attempt to launch without acquisition board connectedScope app will not attempt to launch without PCI to scope interface card connectedI also did a clean install of the Infiniium scope app. I made sure all license files in the scope/bin folder were removed. Then uninstalled and reinstalled Infiniium 5.71.When the scope rebooted after install and launched, it surely loaded with the same 3 options and I still got the "License installation failed" message.Again, not sure if anyone else has seen "License installation failed" message or if this is normal for invalid keys (and not other issues).If anyone could please share proper license key entry method, and normal error message for incorrect key that would be great.So while I cannot launch Infiniium without acq board or PCI card installed to see if it will load options, I removed the bottom cover just to have a quick look at the acq board itself.This contains all of the analog front end, digitizing, and capture memory. Good news is that I do not see any memory/flash ICs other than the acquisition DRAM itself. The rearmost board contains fancy regulators and also distributes power to fans.Never seen a high res picture of this board online so figured I'd be the first. It sure is pretty. Layout is pretty straightforward from microwave front end, ADC, FPGAs for pumping memory into DRAMs.Looking forward to your thoughts on the option related issues.In the meantime I'm going to get a new PCI to scope card, as my primary suspect for external option config flash is the 48-TSOP flash IC on that board.

content: So when I enter a random key, or no key at all (completely blank), and press "Install License", I get the same exact message:"License installation failed. Please contact Agilent technical support".I have not seen any other messages, no matter what I type in the license key box.Is this normal for blank or invalid license keys?

content: Yup, I've tried putting the license.dat, license.dat.bak, and Licenseserver.dll files from the original scope/bin folder back into the right directory.I put the same files in the attached zip.

content: Reviving again. I ended up sending my DSO81304B to an expert in Infiniium scopes. I have been working with him for a while, and we are still tackling the display and option issues.A few takeaways I have learned from working with these scopes so far (and Agilent/KS gear in general).- Each product line (scopes, spectrum analyzers, signal generators, network analyzers) is made by totally different teams at Agilent/KS. This is why all the naming conventions are different, software suites are mixed, and things like licensing and service are also stratified.- DSO80K units have two motherboard versions, Intel D915GUX and Adlink M880 Nitro. The D915GUX does not have on-board LVDS driver, so it uses an Adlink PCI-E card which communicates with the D915GUX chipset using intel ADD2 protocol. The PCI-E card converts ADD2 to LVDS for internal display and also controls the backlight inverter. M880 nitro is a custom board by Adlink which includes LVDS driver on board, so no card is needed.I also bought a DSO80604B recently which has the D915GUX mobo and is fully working. To try and recover the 81304B display issues, I copied U4 EEPROM from the Adlink PCI-E display card in the working unit. To be determined if this fixes display issues.See attached bin/hex files for U4 eeprom contents from working unit display card. Maybe this will help someone someday.
