problem locking Switch in GrandMaster mode to one GPS receiver
WR Switch in GrandMaster mode is able to lock to Cesium clock (cesium.png) and HP58503a GPS receiver (hp58503a_gps.png), but I was not able to lock it to GPS receiver in our lab (2a19_gps.png). Attached files are the oscilloscope dumps presenting 10MHz and 1-PPS output from Cesium and GPS receivers.
