Re-enabling options on an Agilent DSO81204A?
(1/12) > >>
swperk:
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

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

I 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?

I 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.

The 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! ;D

On a related note, since this scope is well out of support by Keysight, is there any way to enable more of the options?

G0HZU:
That was a lucky break :)

Did 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.
