Re-enabling options on an Agilent DSO81204A?
tv84:
Make sure that, after your changes, the ID of your scope is still:
304BMY46001306
or show us the System Menu/About.
nexus:
Here is the about page on the scope.
It all appears normal except for missing options and "License installation failed" error message. It always says "License installation failed" no matter what I type in there, so maybe the license keys are just not valid?
Can anyone confirm if I am entering the license key correctly and if the "License installation failed. Please contact Agilent technical support" message is normal for an invalid license key?
nexus:
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?
nexus:
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 there
* Scope app will not attempt to launch without acquisition board connected
* Scope app will not attempt to launch without PCI to scope interface card connected
I 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.

Try to add an option using a random key and see what error message you get.
Edit: Your license file checks out fine, apart from the fact that the first 4 are expired.
