I have a Phillips PM3375 out in the workshop, and I'm using an HP54601A in the radio shack to monitor transmitter RF; with accurate directional couplers, I can calibrate watt meters. Not far away, on a very heavy-duty turntable, sits a 141T with 8552B and 8554B plugins. I don't actually use that very much, mainly to check harmonics.
I was using a Leader 15 MHz analog scope with a cracked graticule (now at our radio club) which served almost as well,at least letting me know if the sound card output has reset itself to 100 percent again, but the digitizer lets me capture peaks and know what I have.
The 141T has an analog storage CRT, writing to a charged grid then flooding the CRT with electrons. It's finicky, and the display is perishable, so my "digital" storage is a digital camera on a tripod.
Couldn't afford Polaroid film now even if I had the camera.

Did HP (or Tek, or anyone for that matter) make any oscilloscopes that were
basically analog scopes, but with the ability to digitize what is seen on
the display (at some lesser resolution than what you might be able to see
on the actual display, presumably)? As I understand it - which may
admittedly be incorrect - some of the older spectrum analyzers are sort of
like this.
