Re: Tektronix 465B Oscilloscope


If you have to turn it CCW to see anything, but it is sweeping then the problem is obviously DC offset. First of all, how does it act in XY mode ?

In the XY more if it is still offset to the right then look to the output amps. My copy of the print doesn't have it, it is in the one labelled "missing pages". If it is centered with the position pretty much in the middle of range then look to the sweep generators or switching.

After a certain point in the chain everything is differential so center the position control and try to see where the voltage imbalance starts.
