Options:
Tx Clock In
The external clock supplied on the interface Clock In line will be used.
Should this clock fail then the modem will switch to an internal backup
clock.
Internal
The modem outputs a clock on the Int Tx Clock Out line for use by external
equipment. The clock is normally generated from the internal frequency
reference. Alternatively, a station clock of 10MHz can be applied to the unit
and used to synchronise all internal clocks and IF synthesisers which
normally use the internal reference.
Receive reference
The Tx clock is generated from the Rx output clock. This is only of any
practical use when the Rx clock is set to Satellite or Station clock.
Station
The Tx clock is generated from the station clock.
