I'm synchronizing my 6683 using PPS from an external source. The incoming PPS has jitter.
I then generate my own PPS (continuous) using the 6683 (All done via the MAX test panel, no VIs).
Initially, the PPS signals stay near each other within the incoming jitter as expected. But over the span of an hour or so, they drift apart from each other well beyond the synch offset. How does this happen? Is the continuous mode PPS not really a scheduled output other than the first rising edge?
Thanks,
