I've evaluated various of their products including the 125 NCOs boards, and
they are worse than 2ns in real world environments.. The m12+ timing
replacement unit also only supports a small subset of the Motorola command set.
It was useless as a replacement receiver for our Fury GPSDO when we
Hello Ed, Azelio,
We should also compare the same parameters. Sawtooth error of the m12+ of
+/-25ns is not its standard deviation, it's max/min. Compare that number to
your 30ns max/min measurement on the 5372a.
Standard deviation of the m12+ is around 2ns with correction. That needs to be

Yes, you're right. Thanks
Hi Ed,
no problem. It's an issue when some companies claim 2ns, when it's really
5ns. Or show phase noise plots that seem to be measurements of just the
oscillator removed from the board and measured in a clean-room environment,
not measurements of the module with all the digital control
Actually I don't have a good reference (Z3815A): I'm still preparing my
first disciplined Rb and have 2 Fluke PM6681s. I'm waiting for my SR620, it
should be on its way to Italy right now. I have 2 TBolts but not yet turned
on. What kind of reference have you used?

The sawtooth error on the Motorola M12+ is about +/- 25ns, while the
CW12-TIM has a sawtooth error of +/- 2 ns, so correcting for the
sawtooth error is not as critical with the CW12-TIM.
The first claim

We (that is my company) use the CW12-TIM (NMEA version) and its PPS wonders
as usual, nothing different from a uBlox LEA-5T or the M12M.

1. Is CW12-TIM compatible with Motorola M12 ?
The CW12 is designed to be compatible with the M12 although there are
some differences. The
