And here is a newer spectrum.

I am having "transient problems". On a 30 - 100 second time scale, I have glitches which pop my spectrum up by about an order of magnitude in most of my measurement band.

  • I was able to capture a spectrum of ~6 averages with no transient glitch by taking many many spectra.
  • I have no "real" reason to believe that this is not somehow coming from my crystals, so I am wary of ignoring it
  • I also noticed <link later post> that my green noise level has some strange behavior originating in the electronics box I built
  • This is at the 3*10^-18 level in rms. I can buy another factor of two here if I did subtraction above 10 Hz, but the low frequency stuff is the other half, and (I think that it) isn't coherent between IR / Green
  • This was taken with the Agilent 35670A
