The context for this query is that I'm looking for inexpensive GPS units with a PPS output to connect up to ntpd.
Is anybody familiar with these units? I just wired one up. The PPS signal is only 1 microsecond wide. The PPS from my Z3801A is 10 microseconds wide. I can deal with that. The extra factor of 10 is inconvenient. (at least so far) The Garmin GPS 18 LVC has a command to adjust the PPS pulse width, but that's at the granularity of 20 ms rather than the microsecond range. I just scanned the SiRF binary protocol manual and NMEA manual and didn't see anything. (But I might have missed it.) -- These are my opinions, not necessarily my employer's.
