TX CLOCK SOURCE
SCT (INTERNAL)
Programs the clock source for the modem transmitter clock to the following
configurations:
TX Terrestrial Sets the TX clock to recover timing from the incoming clock/data.
SCT (INTERNAL) Sets the TX clock to operate from the modem internal clock (this also is the
fallback clock).
Note: When loop timing is enabled, SCT (LOOP) is displayed instead of
SCT (INTERNAL).
EXT CLOCK Sets the TX clock to operate from the EXT-CLK clock. Transmit clock source
must be phase/frequency locked to the data that is being transmitted. The
correct frequency must be programmed into EXT-CLK FREQ.
Upon entry, the current TX clock source is displayed. Press [
↑ ] or [↓ ] to make the
selection. Press to execute the change.
