Re: TDS 500 600 700 series calibration

Consistent with the self-test complaining about cal if you mix boards between units. I do know the NVRAM holds purchased options. When I used to calibrate 520s and 540s I would pull the NVRAM, copy it into a fresh Dallas part, reinstall it, and then run the cal. Now I wonder if I was wasting my time. But I do recall a NVRAM location you can edit and turn on the FFT.
Do you know what part fails when you get the CalFails?

As far as I know they are in flash ROM on the Acq board and other than screen grabs (or Waveforms) the NVRAM also contains stored settings.
