OK, I have just wasted 2 hours trying to decode the crap user manual.
When I follow the user manual for the "FILE" operations, or if I also look
at this webpage;
https://www.siglentamerica.com/operating-tip/save-file-ssa3000x/then the only thing that happens is a get a screenshot of the entire FILE BROWSER window,
NOT of the spectrum analyzer trace and screen text. I tried this multiple times, to external USB,
using half a dozen file names, and each time I get a full screen picture of the FILE BROWSER window
and not the analyzer trace screen. Google was NOT my friend for this, nor was searching youtube.
They sure took great pains to make this less than obvious.
Help please?
Cheers,
