Hi Corby, very interesting. I have some questions? 1) it is difficult to read the frequency value on the plot. Can you specify? 2) how do you set the offset of the op-amp trimmer ? 3) do you think is possible to use the -20V on the HP5065A instead the -12V from the DC-DC converter? 4) what frequ

Re: [time-nuts] OXCO Spurious Output at Line Frequencies

Hi, I agree with you. Some HP spectrum analyzer have  internal 50 and 100 Hz spurs down to -80dBc due the fan as described in the manual. It can be the spurs are from the test set and/or connection cables. If your oscillator is battery powered you can be sure the spurs are not from the source.
