We haven't gotten to that stage yet. We are first trying to establish we can see the x trace with adjustable markers.

The HP8600a/8601a combo displays markers by briefly interrupting the sweep to produce a bright spot. Chris's scope is displaying that but he doubts it is the marker spot. I would like to prove that it is.

The marker frequency is read from the display of the HP8600a. The whole idea was to be better than beating the a separate RF spot frequency marker with the RF sweep to create a marker blip on the trace. It is supposed to minimize distortion to the swept signal.
