If Intfc1 Rx Buffer: Æ Size is selected:
Intfc1 Rx Buffer Size:
10.0 mSec (0343,680 Bits)
The range of Rx Buffer Size values is from 5.0 to 32.0 mSec in 0.1 mSec increments. To edit, use
the
W X
arrow keys to select the digit to be edited, then use the
ST
arrow keys to change the value
of the digit. Press
ENTER
when done.
If Intfc1 Rx Data: Æ Recenter is selected:
Intfc1 Rx Buffer Fill:
(046%) ReCenter (
E)
The percentage (046%) indicates the current buffer fill status. To reset the buffer to the midpoint
(50%), select

.
If Intfc1 Rx: Æ Clock is selected:
Intfc1 Rx Clock:
Source Invert (

If Intfc1 Rx Clock: Æ Source is selected:
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-Terr
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.
If Intfc1 Rx Clock: Æ Invert is selected:
Intfc1 Rx Clock Invert:
Normal Inverted (
E)
This selection controls clock inversion (added for compatibility with certain older equipment).
Select
Normal or Inverted using the
W X
