Interesting, I will look into it as a way to get a starting point, atleast
for initial tests and diadnostics

Well in the world of Linux/Python, processing, math and plotting, these are
not really big difficulties

The 5372 uses a weird video-format, 19KHz horizontal and 60Hz vertical,
but it might be possible to find a LCD panel which can do that.

There are two bits of video, "half intensity" and "full intensity", so
a color panel would be required.

I've never quite gotten the hang of HPIB with the HP5372, the HPIB
is very geared towards moving the raw binary data, and not very
much towards "remote front-panel".

You can get a bitmap of the screen using "INTERFACE;PSOURCE,DISPLAY;PRINT",
but it is not particularly fast and comes with gratis PCL escapes, but it
does work.

If you dump the raw measurements, that's precisely what you get, and you
will
need to do all the processing, math and plotting yourself.
