I'm working on a preamp for a low frequency signal; the bandwidth is less than 300 KHz. I'm looking for a spectrum analyzer that works well in this range; about 1 Hz to 1 MHz would be ideal. Does anyone have any suggestions on a good analyzer for this application?
I'm looking for better than -90 dBm sensitivity; the digital scopes with FFT drop out at -60 dBV (about -47 dBm, so not even close).
Along the same line, does anyone have any suggestions for low frequency FET probes? I'll need to monitor the signal without loading it. I can use my old P6201, but then I'll have to drag the 7834 along to power it up!
