Sala,
I have an SDRPlay RSP2 that I have used as a spectrum analyzer with the RSP-Spectrum-Analyzer software.? ?I would say that it is good for checks below 40 MHz, so good for tight in spurs detection, and OK for harmonics up to 40 meters (I have not tested 30 meters, as no interest there).? When testing for 20-meter harmonics, I am getting a spur around 53 MHz that may be related to the USB clock.? The one thing that I do use it for that seems to work well is two-tone testing.? The RBW seems to be small enough to see both of the tones.
I have ordered the RSP1A to see if that unit has a better response above 40 MHz.? It also has a 14 bit DAC, as opposed to the 12 bit in the RSP2.
The above are my opinions based on my experiences so far.? Yours may be different.
