When I was (playing) testing with my Nose source noise source and TinySA, everything was fine at lower frequencies, but when the max frequency was 5GHz, there was a 10-20dB step at 3GHz. I don't think noise source does that,? but I wouldn't think TinySA would do that either. I ran calibration after this and as always it passed. Should TinySA Ultra be calibrated before use?
Yes, in the noise source PCB, there is a text NOSE SOURCE.

By the way,? the noise source runs very hot at 12V. Amplifiers? in it may do? something extra.
