you can launch scope.exe using the service command " scope.exe /service" that gives extra options in the self test menu where you can set attenuator click and othe roptions

Apparently you can hook up an IDE CD ROM drive on the secondary IDE channel though so I'd try that path, especially if you have one laying around already.TonyG
I tried to install XP but the problem is that the drivers for the acquisition card are not available. The Windows98 drivers won't work on XP because XP is completely different when it comes to drivers.
Holy freaking crap! I followed through this article and did some measurements: http://www.dasarodesigns.com/projects/fixing-an-hp-agilent-54845a-infinium-oscilloscope/And guess what? In my scope the -3.1V supply shows +0.8V, same as in his scope! So it is probably failed opamp in my scope too! Could it really be so simple? Going to order few LT2726 IC's ASAP...
I got finally my scope today. Very big surprise when power up, start …. Boot ….. no error …. Pass al tests.
