If you know the H frequency (or the refresh rate and resolution which can be used to calculate it) and the drive signal amplitude and have a function generator that can produce a square wave of the right amplitude frequency and duty cycle then you could potentially get the monitor to produce a raster....If you achieve that you could get a rough idea of emissions and cutoff over signal range by hooking up a NTSC composite video source to the video pins (it won't be in sync but would give grayscale a check).

I believe the H is 18.432kHz and V is 50Hz. Wish I had a way to generate the signal. Might be nice to have one for future, but the video card will be here before I could get a generator.
