Having several spectrum analyzers including the SA44B, I find myself using the Hound more than I expected at first. It's size and portability is perfect, and it uses the USB for power.
Now one thing I still have problems with is that the RBW is somewhat related to FFT bins rather than 1:3:10 that we are used to.
But honestly it's more a mental thing than limiting the usage.
Sweep times are not too bad most of the time, but wide sweeps cand take longer time than one is used to. The Hound have a 250 kHz wide IF that is digitalized, and narrow sweeps are quite zippy
Phase noise is not too bad, and the phase noise measurement utility quite nice, and so is the harmonic measurement.
Sensistivity is great, but the attenuator seems to be distributed in the signal chain rather than at the front as sensistivity can go down with less attenuation !
Saving plots, changing colour of traces, having several delta cursors makes it really simple for documentation. No need to save trace first, just use the clip tool in windows and paste into your document.
