Certainly the 18xLVC has a PPS pulse, as does the 18x-5 OEM which is a 5PPS. It give about 1us accuracy, not 10ns which is what some might call timeing GPS. But that 1ns is pretty useless for computer timing, since a computer really cannot use better than about 1us accuracy. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
