Even THD for 1 kHz would only be able to use four harmonics.
Four harmonics ??
Four harmonics ??
Sorry. That was totally wrong. My brain was not working well, obviously.
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

Jesper, 100kHz lower limit seems to be misaligned with this threads aim, unless your post was a sales job ?
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
