Does anyone have code which will take an amplitude vs. time input stream and output phase noise and/or allan variance?
Thanks, Matt P.S. I was forwarded a message from the list about the USRP. The USRP does have an input for an external clock source, so feel free to feed it from your Hydrogen Maser or whatever else you have laying around :) The reference needs to be at 64 MHz or lower. You ADC sample rate can be 1/4*fref, 1/2*fref, fref, or 2*fref, as long as the final rate is <= 64 MHz. The DAC sample rate will always be 2*fref.
