Martyn, The Cable Delay Correction command (@@Az) has a limited range (0 to 999999 ns), but the Time Offset command (@@Ay) does not. From the M12M manual:
The 1PPS Time Offset command allows the user of M12M Timing Receivers to offset the 1PPS time mark in one nanosecond increments. This offset can be used to place the 1PPS signal anywhere within the one second epoch. So although the effective value is a combination of the two, I think the idea is to use cable delay command for just that, then use the time offset command to position the 1PPS pulse anywhere you want it within the one-second window. 73, Brent, KD0GLS, Minneapolis On 27 Jun 2013, at 11:50, Martyn wrote: > Hello, > > I have been asked the following by a customer: > > The M12M GPS receivers have two ways of compensating for antenna delays. > > The @@AY and the @@Az commands. > > So the 1 pps output can be moved forward in time to compensate for antenna > cable delays. > > Does anyone know whether it is possible to move the pulse the other way? > > Thus to enter a negative figure for the cable delay compensation and move the > 1 pps back in time. > > Best Regards > > Martyn > > > _______________________________________________ > time-nuts mailing list -- [email protected] > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts > and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
