The minimum frequency of the SAA2 is listed as 50 kHz. The minimum of the H4 is listed as 10 kHz. It doesn't look like it will work. You might squeeze in the upper edge of your range with the H4, but not the lower end.

I have a question about measuring filters below the low end of any Nanovna.
Is it possible to extrapolate both S21 and S11 down to DC on the Nanovna? I am looking for a way to measure some low pass filters I built from 0 to ~20KHz (audio range) without costing a ton of money. I do not have access to a Frequency Response Analyzer. Any thoughts or suggestions would be very much appreciated. Thank you, Ken M.
