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...

The Tektronix 528A waveform monitor lives again! Huzzah!
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.
signal // noise — CRT + Vector | test 03
Sony Hi8 CCD-TR680E → Electronic Visuals EV4061 (waveform monitor) → Goodmans C210 (CRT TV)
First live test of the EV4061: signals pulled through the Hi8 tape path and re-emitted in green stripes of pure waveform language. Simultaneous output to CRT provides recursive contrast—sine hum vs scanline fuzz.
Next step: record direct to VHS, bypassing CRT, to explore tape glitches, signal decay, and tracking artefacts. The analogue stack keeps growing. The ghosts are getting closer.
