What could Account for This? RCA 9TC-240 Power Issue

[Chris K]

Supposedly the 369 is supposed to be good for this kind of sweep generator stuff but since I’ve never used it successfully who knows. There’s a respected ebayer who makes replacement rf output and demodulator input cables for it and I got them. The scope output is a strange output style though and to be “NoobHonest” I have no idea how to hook this output to my scope. They show X-Y connections and say to use your scope in X-Y mode etc and that’s where my head starts to spin. Frankly my scope experience is hooking the probe to a test point and ground, pushing Autoscale and comparing the trace to a photo. That’s about it.
