Phase Noise Measurement 3.125MHz Squeezer Signal

M. Pirello, R. McCarthy

We measured phase noise on the 3.125MHz source located in the CER using the BluePhase 1000 Phase Noise Test System.  Unfortunately data taken with the SR795 was corrupted on the thumb drive.  I did take notes, though they are not as thourough as the spectrum data.  I have attached a plot of the phase noise measured yesterday on the Tektronix function generator, and compared it to the phase noise measured today (3 datapoints).  Daniel wants more spectrum measured between zero Hz and 10kHz, so we will continue this measurement into next week.  I have attached what we have as of today.
