Which Spectrum Analyzer Measures Very Low Frequencies?
<< < (4/7) > >>
JohnnyMalaria:
I don't know what the budget is but if you can find an HP3582A, it will do nicely. I used one extensively many moons ago. It's 2-channel digital 0.02Hz-25.6kHz.
tecman:
My Advantest R9211C covers 0.01 Hz to 100 KHz

The latest Siglent oscilloscopes seem to have a pretty impressive FFT capability, and the scope's go down to DC. FFT is much better than you would expect from an 8 bit ADC.

The FFT of my Rigol DS1052E is no more than a toy.

Alternatively you might look into seismic equipment, or PC software such as Octave or Matlab.

I have both an hp3562  DSA and a silent sds1104x-e (hacked to 200mhz) and there is absolutely no comparison, the fft function on the sds1104x-e doesn't even come close to what the HP DSA can do.. i mean not even worthy of being in the shadow of the DSA its that far different. 

I suppose if you got nothing is its something, but, frankly from a usability standpoint and doing real readings and analysis... it is a toy compared to the DSA.

What is special about 9kHz that makes it the lower bound for so many spectrum analyzers?
