Setting Input Priority Values

The TP 5000 uses the Priority settings for each qualified input port to determine
which input port to use as the reference. Priority values can be from 1 to 16, where
1 is the highest priority level. If two input ports are set to the same priority value and
both are qualified, the predefined preference is used (see
preference has the same value as the default priority value, but cannot be changed.
Reference selection among inputs with the same priority is non-revertive.
In Time mode, time references are selected first, even if a frequency reference has
a higher priority setting than the time references. In Time mode, there must be at
least one qualified time reference for the system to get out of the warm-up state and
into normal track state. If all time references are disabled or disqualified after the
system gets to a normal track state, a frequency reference will be used for time
holdover.
In Frequency mode, all reference inputs (time reference and frequency reference)
are used. The reference selection is based only on priority.
Note: With t
GNSS port can receive Beidou and GPS satellite RF input. The
GNSS track-mode parameter is used to specify the tracking
priority for signals to the GNSS port. See
