New piece of test equipment for the workbench:

Tektronix 1730 Waveform Monitor

Now I can monitor all the waveforms. Just need to find a 1720 Vectorscope to go with it...

Recently, someone was asking me about dedicated waveform monitors for verifying video signals. In a pinch, if you don't have a waveform monitor (like me), you can use an oscilloscope to the same end. Here's my Tektronix 2445B showing a simplified set of 75% NTSC color bars. Trigger the scope on the falling edge of the back porch within the signal, and adjust scale and timebase from there.

I'd love to find a calibrated rack mount set of 1720 and 1730 models from Tektronix, as they're a quintessential pair of dedicated waveform/vectorscopes for broadcast signal analysis from the good ol' days.
