Magnus inspired me to try my own cross-correlation experiment with the
TimePod today. I used two fairly normal OCXO frequency standards as the
reference, and a Wenzel 5 MHz ULN as the device under test.
By doing single-reference measurements of each OCXO versus the ULN, I
was able to plot their noise. Since the ULN has performance near the
noise floor of the TimePod, I could then test how well the correlation
works to allow measurements below the noise of either reference.
Conclusion: it works *really* well. Plots and a little write-up are at:
