Is 1PPS used if I have GPSDO installed or does the B200 assume that 10MHz is already good enough?

There is no internal PLL that is phase-locking to 1PPS--the assumption is that the 1PPS is locked to 10MHz already, and it's just used as a trigger for TOD (time-of-day) setting operations. -- Marcus Leech Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org
