Very nice! Up there with the best of them. I'm curious about the measurements that are showing 100 kHz PN values in the -183 dBc/Hz neighborhood on your E5052B ( www.ptsyst.com/10MHzPN-2.pdf ) but only about -177 dBc/Hz on the TimePod ( www.ptsyst.com/10MHzPN-1.pdf ). Was the same pair of oscillators being measured in both cases, and was the TimePod being used with dual independent references or a single reference?
With dual references on the TimePod you should see results similar to the E5052B, but it looks like you used a single reference for the PN-1.pdf plot. Something that reaches -176 by 10 kHz and then flattens out.
