Hi all,
Just briefly resurrecting a previous thread to mention a very affordable spectrum analyzer I recently bought: The tinySA. More information is available here:
https://www.tinysa.org/wiki/
In its "high-res" configuration it spans the region of 0.1 - 350 MHz which in my context has proven sufficient (950 MHz with reduced precision). And depending on settings it seems to be sufficiently precise down to ~- 100 dB levels, which is good enough for me.
And I indeed like its size and the fact that I don't need a huge device on my table while working. And should I need a high-res image I can connect it to my laptop/monitor via USB.
Price is around EUR54 here at eleshop.eu:

Just mentioning it in case somebody else may be interested
Cheers, Jesper

Hi both ...
I reckon we are probably thinking about two different objectives here: As far as I can see the QA403 is for audio frequencies whereas the one I have linked to is much higher up in frequency. I use it to look at noise on digital PSU lines, EMI qualification, etc. ... frequencies where an audio analyzer normally doesn't go.
I have no affiliation with this product - was just trying to be helpful in case someone here was looking for a price-reasonable spectrum analyzer
Cheers,
Jesper
