Hi Pete, I snapped on the osci probe and see no 1 PPS or 2 PPS signal. It seems like a noise signal with several positive and negative spikes with an peak to peak value of 50 to 60 mV... disapointing... Next is to analyze the rest with a logicprobe but the signal level seems to be too small for beeing a logic signal... TTL should be at 15 V, CMOS 5 V... but 50 mV ?
