Also, pairing it with the Omnipod 5 is just next level. Closed loop. Never having to inject in public. No tubes.
I found, for what I do, having a vector network analyzer was more useful that having a spectrum analyzer. Specifically, measuring the SWR of antennas and measuring the resonance frequency of filters.
But the signal was intermittent, and I talked to all the neighbors in all three units, and none had anything that sounded like it could be the culprit. It eventually just stopped happening, so I never tracked it down.
This is a great explanation of the signal path: https://www.youtube.com/watch?v=z63cXhYzS1A
I don't think you are going to find much for less than a Picoscope.
Maybe something like the Analog Discovery 3? Under 400 USD, 2 channel oscilloscope (30 MHz), 16 channel digital, 2 channel arbitrary waveform generator (12 Mhz) https://digilent.com/shop/analog-discovery-3/
Rigol and Siglent both make mixed signal scopes that will do two channels analog at 100MHz and 16 channel digital for ~1k USD.
Still would have looked nuts with the TinySA, but... less so.
Fun fact, the famous actress Hedy Lamarr actually was instrumental in inventing it!
Another cool tip is to use NanoVNASaver (https://nanovna.com/?page_id=90)
These are very cool and fun, but I found myself using my NanoVNA a lot more than my TinySA
Reminds me of this onion article: https://www.theonion.com/girlfriend-stops-reading-david-fost...
The never-ending footnotes did amuse me though.
I've never gotten around to reading "A Brief History of Time", but I still hold out delusions that I'll get through "The Road to Reality" by Roger Penrose some day.
Can also make a Raspberry Pi act as a transmitter (https://github.com/F5OEO/rpitx), which could hit the zwave frequency but not the zigbee one. (Also, make sure to put a low pass filter on it.)
