Workout for scope and hifi.

[Diabolical Artificer]

I have several scopes that have separate ext sync or horizontal IP. A HP 120B which is a single ch scope shows these visualizations/lissajous patterns well. My Tek 585 also has ext horizontal IP as well as several other ins and outs which I havn't figured out to use like + gate A and B, delayed trig, and ext rigs for both beams. It also works on my Tek SC502 which has timebase off on the hor timebase knob.

This facility is also very useful for curve tracers. I have built a simple component tester like a Octopus that you can use to test diodes, caps etc. Keep meaning to build a proper curve tracer but busy fettling the big amp.
