I have no affiliation with this product. I've used it to fix
intermittent connections that drove me crazy. It's not a contact
cleaner, and you'll have to read the details to understand what it does.

Meditating on this a bit, I assume in a strict sense, you can only consider
GPSDOs phase locked if they are disciplined from the same GPS.
Or is this being pedantic

According to http://www.realhamradio.com/z3801a-turning-point.htm they
use a HP 3575A phase meter to perform the measurement.
Or perhaps I have misinterpreted the whole thing?
5370Bs were a $20,000 instrument
How about just running the two different 10 mhz outputs into a doubly
balanced mixer and monitoring the DC output with a volt meter from the IF
port of the mixer? Sure beats $20,000 for a fancy HP. Of course this is a
very simple method and is boring as heck to sit and watch a voltmeter but it
I'd like to perform some comparison between a known good GPSDO and some
newcomers.
I want to adjust the crystal turning point as my new GPSDO tend to wander all
over the place.
I see some of you are using the hp 3575A to do this.
Unfortunately, they are a little out of my price range at the
Hi
FIrst step is to fire up the 5370B counter and see if it works. If there's a
problem re-seat all the boards and see if that fixes it. Simple way to check it
is to let it count it's own reference.
Once you have that working, then yes, measuring time between PPS outputs is the
way to go.

GPSDOs phase locked if they are disciplined from the same GPS.
