I found I could add X out and Z in on the blank panel on my Hameg. The schematic had the locations marked. I didn't figure Y out yet. I first amused myself doing this in the BBC CTA in 1970s.
Handy for not just TV, but you can feed Z with the Pen Up/Down signal on some random piece of gear. Or have a "marker" function, (calibrated tuned filter with detector, such as "Dip Meter" on the output of a sweep gen driven by X (to brighten or dim the trace). A detector on the equipment under test (RF or IF etc of TV or Radio) feeds the Y in.
