Audio Analyzers (but not a toy)
KungFuJosh:
I've been interested in getting a spectrum analyzer, primarily for audio equipment testing, for a while. This seems to be a weird quest for some reason. It seems most suggestions are to lean towards basically any sound card for a computer, but I'd prefer something standalone, unless there's something 'attached' that's really nice. I'd also like the "instant gratification bode plot" feature. 😉
100Hz to 20kHz would be the absolute minimum range, but down to 10Hz or 20Hz would be better. It seems the fancier new SAs all bottom out at 9kHz for some reason.

SA are primarily RF instruments.
SA for audio are called audio analysers and there are many of those.
You won't like the price.
Take a look at Quant Asylum.
Or stick with audio interfaces...

I've got a 35665A which is built exactly for this purpose, and in all honesty lately I keep thinking about getting rid of it and using a sound card instead.
It's nice having a standalone thing on the bench that you can just plug into and go, but it's also pretty slow/limited compared to computer based solutions.

If you can live with 1/3rd octave steps maybe something like the old klark teknic dn60

I’m using an external pro USB audio interface, 24 bit resolution with 192KHz sampling rate. REW is an excellent free app for spectrum analysis, I also have Jupyter notebook to do the same FFT Rew can do. Tons of discussions on how to do it and what interface has the lowest noise floor and distortion - see https://www.diyaudio.com/community/threads/how-to-distortion-measurements-with-rew.338511/
Back to you post - it’s attached, and REW updates the spectrum display real time on screen. Can generate signals too, however it’s not as good as a standalone precision Wien bridge. Much discussion on that too.
