Hello,
My HP-85462A - now obsolete but still useful - displays a not documented 'CAL: gain error' when calibrating the amplitude. Just before that error occurs, the display shows that an adjustment cannot be done: the response curve amplitude is adjusted but not enough to get it not saturated. It still exhibits clipping. A few tries later, the error message is displayed, and the calibration routine stopped. Any hint about this issue?
Thanks a lot,
Bertrand
