Previous 4 GHz test was due to lack of test equipment. Might cause confusion.

Almazny theoretical minimum frequency is 6800 MHz, see: AD5356 datasheet page 4

Slow down attenuation update for better capture on TinySA.

How does it look on tinySA?

The commit message didn't mention "Slow down attenuation update for better capture on TinySA.". Split the commit into two and update the title

Also what the RBW setting did you use? A larger RBW should speed up the capture speed. A smaller span helps too.

The default setting on TinySA takes about 1.2 per scan at 500MHz span, 850kHz RBW, 450 sweep points.

The fastest setting that I think are clear enough is about 0.8 s per scan at 350M, 850k RBW, 100 sweep points.
