I have my GPSDO developed well enough now that I'm correcting for the quantization error given by my LEA-6T. As I watch the phase difference plot, it seems a bit more noisy than it should be. I've also had to make the DAC pretty active to keep the phase noise on a short leash. So, I'm wondering what I have around here that I can use to measure the phase noise of my OCXO.
For test equipment I have: My ex-telecom Rb that I turned on last night showed poor frequency stability over night, so I'm going to let it bake for a day or two to see if that improves. An HP 10811 standard in my 5335A, and the 5335A itself to measure time interval. I have GPIB and I can capture the TI from the 5335A. An ADR-291 Voltage Reference to lock the EFC of the OCXO to a known value. My thought was to begin by locking the DAC to a single value and plot an ADEV against the Rb. Is there anything else I can do with this somewhat primitive time lab?
