Several of you have talked about using XY displays for this. I'm probably
just dense, but I don't know what this
is... Can you provide some model info that I might look up. I'd love to
have this clock displaying on something
other than my Tek scope

Hi Mark
An X-Y display is similar to a scope but the inputs interface directly to
the X and Y plates of the tube via DC amplifiers.
What's missing are the timebase and triggering circuits and the AC coupled
vertical amps and attenuators.
They are commonly used with instruments that generate their own timebase
waveforms, such as sweep generators etc, where the sweep waveform will be used
as the timebase and will be conncted to the X plates and the detected RF, say,
to the Y plates.
Most scopes can be used in X-Y mode anyway but the X-Y display is really
just the back end of the scope without the fancy twiddly bits on the front:-)
