Hi Mark,
good job.
Have you made an analysis of the results and made some considerations about
the parameters you have measured?

I recently completed some comparison tests of the PPS and 10 MHz outputs of 17
different GPSDOs.
The tests were done with a TAPR TICC time interval counter running in timestamp
mode and the data was acquired and processed with Lady Heather. The TICC was
clocked by a HP-5071A cesium beam

Not on the physics package of the CSAC. As I understand it, the vacuum
around the physics package is more for thermal isolation than anything
else. You can tell that the vacuum is fading because the heater

That used to be a requirement on this sort of thing.

You might be surprised by how well the CSAC does in orbit. There have been a
lot of cases
over the years where a device has done much better once it is away from “poking
fingers”
like pressure and other semi-random stuff ….

Oh, I'm pretty sure

In LEO for testing ? Otherwise the name seems a

I'm considering purchasing one of these units, but would like
to know just how bad/good is bad/good before I leap. I'd get
the most useful info for the case of all modulations OFF,
"perfect" external reference, and for a reasonable assortment
of RF frequencies (or one frequency plus a statement
