Frequency
Identifier Values Description
FREQUENCY Hz
Source frequency as measured relative to GNSS locked
PPS. If the GNSS is not locked, the value will not appear,
and the flashing Rb holdover indicator will appear.
ERROR ppb
Calculation of frequency error in ppb relative to the
GNSS PPS. If the GNSS is not locked, the value will not
appear.
GATE s
The sample period of the frequency counter, which
expands up to 50 seconds as valid data is acquired.
PPSRB ns
Difference between the GNSS PPS and Rb PPS as
reported by the Rb module.
ACCY
ns/ns
<estimate/threshold>
Estimate of current PPS accuracy provided by the
GNSS receiver vs the current accuracy threshold needed
to produce discipline and monitoring. High values
(greater than the threshold) indicate the unit or the
antenna should be moved to a better view of the sky.
PPSRF ns
Difference between the GNSS PPS and Rb PPS
