Correct - I'm unable to change the scope back to a DS2072.
I don't know if it is of any help but I'm on firmware 00.01.00.00.03
Man, it doesn't sound like you've read the correct way to do it - even after Wim pointed you to the precise page of this thread that explains how!
Seriously - read that - try it - and then come here to complain you can't do it.
I unknow the
page you are referring to and, among the other tests, I also I did what the post says.
This what I did.
1.
I used the code LLLLLLL-RLGLLDS-
VSA9LLL-LLLLLLL via the scope user interface
Run a self-calibration
2.
With Ultra-Sigma (LAN and USB) I run the command:
:SYSTem:OPTion:INSTall LLLLLLLRLGLLDS
VSA9LLLLLLLLLL
3.
With Ultra-Sigma (LAN and USB) I run the command:
:SYSTem:OPTion:INSTall LLLLLLLRLGLLDS
VSA9LLLLLLLLLL
followed by
:SYSTem:OPTion:UNINSTall
4.
With Ultra-Sigma (LAN and USB) I run the command:
:SYSTem:OPTion:INSTall LLLLLLLRLGLLDS
DSA9LLLLLLLLLL
followed by
:SYSTem:OPTion:UNINSTall
5.
With Ultra-Sigma (LAN and USB) I run the command:
:SYSTem:OPTion:UNINSTall
After each test, I did a power cycle. None of the above worked.
