There is a mod that replaces the on board 66 MHz oscillator with one locked to
10 MHz.

Hi
In a DMTD (or in the equally useful single mixer setup) the advantage for
frequency measurement
comes from the downconversion process. The further you downconvert (10 Hz vs
100 Hz) the

Hi
Just to clarify:
You are looking for a way to digitize the output(s) of the mixer(s) in a DMTD.

A number of posts have appeared about Zynq SDRs on the "Shera revisited"
thread. So, I'd like to ask the more general question: Are there any low cost
SDRs that are suitable for measuring phase noise when coupled with a DMTD? I
believe what I'm looking for is something with enough bits to
