Intfc1 Rx Clock:

Rx-Sat Tx-Terr Internal

This selection determines which source clocks the output of the Rx Buffer for delivering

data to the Rx port at the user interface. Select Rx-Sat, Tx-Terr, or Internal using the

W X

arrow keys, then press

ENTER. Note the following:

Rx-Sat

(default)

Effectively disables the Rx Buffer because the input and output clocks are the

same. Normally, the Rx Buffer is set for minimum when Rx-Sat is selected.

Tx-Ter

Uses the clock from the Tx input (TT) to clock out the Rx Buffer.

Internal

Derives a clock from the internal 10 MHz reference clock.
