Yes, many devices, both professional and amateur, use a precise 1PPS signal to discipline Qz, Rb, and Cs frequency standards. Almost every GPSDO on the market is based on a 1PPS discipline algorithm.

Application Note 1272 http://metrologyforum.tm.agilent.com/pdf/AN1272.pdf I'm curious about the 10 kHz signal. Can you send me a pointer to it? Usually 1 Hz is good enough and in practice most GPSDO use an averaging algorithm that is more akin to 0.01 Hz to 0.001 Hz. /tvb _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
