Re: Tek 465: CH1 No signal, CH2 signal reads a fraction of input, V Pos distorts signal


Just wanted to add another observation:

If I calibrate V amplifier bias for maximum deflection (as per service manual), I no longer experience signal distortion and expansion or compression when operating the V pos dial. However the signal shown is 350mV, instead of the 300mV supposedly delivered by the onboard calibration.

I should be able to get hold of a second (and calibrated) scope in the upcoming weeks and make more accurate readings.
