Folks,
a good friend of mine got his hands on a surplus FLUKE 103 frequency &
phase comparator. Has anyone of you a manual of this device that he can
share with him? Or a pointer to to a pdf on the web?

Surely you can build a frequency standard in this way, but be prepared
that it will not be a good one! Take a look at

The M12+ reports the error in the PPS position. If you make your
measurement, then add in its estimated error, you can get that level
of precision. I'm not sure how you

Well, thanks for the advice!
...And also one other convincing (at least for me)

The M12+ has a choice of either a 1PPS precise signal
or a 100PPS precise signal. For my application (GPS
disciplined frequency standard), the 100PPS option
will surely help settle the frequency for the few

use for our cabling."

The M12+ achieves 2.9E-012 at 1000s intervalls.
The M12+ is speced at 10ns 1-Sigma, the Trimble seems to be 15ns at 1-Sigma.
There is an M12+ follow-up modell comming soon which is even better tha
