Programmed Green = PFRU is programmed, Red = fault
Communication
Health
Green = Serial communication OK with PFRU FPGA, Red =fault
Sys Reference Clocks
External 1PPS When selected as the 10MHz OCXO Reference, Present = Green background,
Missing = Yellow. A Blue background indicates this source is not selected as the
10MHz OCXO Reference. This input is derived from the customer’s GPS
receiver.
External 10MHz When selected as the 10MHz OCXO Reference, Present = Green
background, Missing = Yellow. A Blue background indicates this source
is not selected as the 10MHz OCXO Reference. This input can be derived
from a variety of sources. See Table 3-17 on page 36 for more info.
Internal GPS 1PPS When selected as the 10MHz OCXO Reference, Present = Green
background, Missing = Yellow. A Blue background indicates this source
is not selected as the 10MHz OCXO Reference. This signal is derived
from the transmitter’s internal GPS receiver.
