I have a 535A scope with CA plugin. I have both A and B channels working just fine.
The problem I am having is that when I switch to either "Alternate or chopped Mode"
only one line appears on the scope, not two, one for A and the other trace line for B Channel.
Besides that, both A and B vertical positioning knobs can move the line up and down. That should not be.
I have replaced tubes 154 and 145 and exchanged tubes around in the CA module. Did not help.
Any help would be appreciated.
cheers
