Well the 7200A has arrived!
There is output on the VGA port at the rear but during boot it gives a blue screen and then resets. I'm going to try a fresh install on an SSD first.
Remember to preserve D:\Calibration directory from the original HDD!
That is going to be a problem... Meanwhile I managed to re-install Windows XP on an SSD and start the oscilloscope software but I have found some issues:
1a) The factory calibration data is missing. It seems there is an extra partition on the original drive but Windows XP says it is not formatted; I guess the calibration data is stored here. I have not made any attempts to restore the partition.
1b) I ran the self calibration routine. Is this enough to have some basic calibration or are the factory calibrations mandatory?
2) The oscilloscope keeps clicking relays and the waveform update is really slow. A new trace every few seconds.
3) Channel 2 seems to have a problem with the attenuation. Channels 1, 3 and 4 seem consistent
4) The traces appear to be very noisy (full bandwidth) coupled 1MOhm from the aux output (1kHz 1V)
5) I tried to run the self tests from the service menu but it says failed immediately without a message
