I already have a scope which I use on my work bench, but it sits a lot
not being used, so it would be kind of handy to plug in a device which
would enable it to be used as a SA or panadapter type scope for the
shack. This would make my scope much more useful. Anything like that
around?


Alas I am not aware of such an item. But there maybe someone else who
does. Heathkit made anumber of these in kit form for thier Amateur
Radio kit and you do see them on Ebay and other places. Designed for use
with the SB-XXX series mostly they do have specific needs as to IF
frequency etc. Thta info is easly available and using it, I'm sure they
could be adapted quite easily to othere readios that have similar IF's.

Scopes are very versatile instruments, and can be used for a number of
purposes right out of the box. The accuracy of results depends on the
"quality" of the instrument. Suitable setup and interpretation of results
will allow you to make Voltage (p-to-p and RMS) frequency, phase
measurements. Newer instruments have these built in and display them on
screen without the need to eyeball the waveform and do mental arithmetic.
Back in the day... the reason an electronics nerd kit included a small
pocket slide rule was to do quick calculations based on the observed
waveform and control setting While it was fun, I much prefer the newer
gear, with its on screen of voltage, frequency etc along with the
waveform.

For me at least the most useful peice of test gear is the service monitor.
Even if you are using it as test gear it can be used as receiver to tune
in local broadcast stations and send them annoying critiques of their
signal deficencies
