For those that want to do very accurate phase and frequency measurements, but are not willing or capable to buy a PhaseStation or Timepod, a new FW has been made available for the nanoVNA-H4 HW that converts it into a mix between a DMTD and PhaseStation.
Accuracy of phase measurements is better then 1e-12 / (Tau in seconds) and the device support sending the phase measurements over USB to programs like TimeLab or writing to an internal SD card for later analysis.
Just to clarify, I take it that it would not be possible to measure the offset and jitter between two 1 pps signals with the nanoPFA? Even if the levels were reduced to the -10/15/20 dBm level? The device isn't intended to measure time differences as such, or could it be?
