John,
Your new three-corner hat feature is really cool. Already tried it, even
if I did not spend quality time on setting source labels correctly.
Whenever I have a setup capable of running it, I will test-spin it again.
I suspect that when you make separate measurements, the noise of
Hello Dave,
That is the same firmware version as mine, I cant tell you if that is
the most current.

Thanks for correcting me there.
In this case, we have 5kHz / 10 MHz = 0.0005, right?
Yes, that would be it.

Hello fellow time nuts,
As many of you know, there was a slow meltdown of the time-nuts mailing list
late last year. We put a stop to it mid-December (see [1] and [2]). The goal
was to get the list back to 10 to 20 high-quality postings per day.
The list was sort of turning into a social

Hi
I have done an 8 hour test with X72 as DUT and FE5650 as Reference.
The data is uploaded to

The HP5370a was indeed in TI mode. By the way what is the difference with

Hi All,
I'll respond to all here, since I'm a little slow at times...
John, This unit has been up and running for at least a month. I've
restarted the GPSDO a few times, but the GPS has remained on. So, if
your unit is up for extended periods of time and you see something
similar, please
Actually I'm working in the RF department of a big lab, designing RF
electronics mainly in microwaves range. I'm luckilly having some tools
around to play with and a lot of components like
mixers/amplifiers/couplers/splitters/attenuators, ... almost whatever
the frequency is up to several tens
Hi Ivan:
I built a number of automated systems for microwave test, see:

It was only when testing mixers for specific spurs where we used the synthesized signal generators for low phase noise
so that the spectrum analyzer could be used with a narrow
