Ok. Let’s try this again…RCA 9TC240 Alignment

Aux out of the 8601 into counter on 8600



Blanking out of 8601 and into 8600




Sweep Inhibit out of the 8601 into the 8600




Sweep out of the 8601 and into the 8600




Sweep out of the 8600 and into horizontal input on scope




8601 on and set for CW at 50MHz. 8600 showing frequency with the scope button pushed in.




8601 set for a symmetrical 3MHz sweep around 50MHz at 0 dBm. Frequency displayed on 8600 shows a stable frequency read with the center button pushed in but actually the frequency display is almost unreadable as it flashes with jumbled frequencies all over the place. No markers on trace. No amount of turning the marker setting control to left and right extremes changes anything.






I've tried all the other marker buttons with no change. Marker height adjustment on 8600 turned up almost full but there's no change no matter what I do. Scope is in X-Y mode.
