2.1.10.4

Deinterleaver (Reed-Solomon Codec)

Depth 8 (Closed Network).

Note: The Reed-Solomon depth 8 deinterleaver is based on the IESS-310 specification for
8PSK and is adapted for QPSK/BPSK operation.

2.1.10.5 Receive

Frequency

The receive frequency can be selected by the user from 3.7 to 4.2 GHz, in 100 Hz steps.
The actual value of offset from the programmed frequency is available to the user on the
front panel as well as the remote port. The resolution of this value is 1 Hz

;

the accuracy is

% 25 kHz.

2.1.10.6

Receive Input Power (Composite)

The terminal can operate to its specified performance under all of the following
conditions:

( The sum of all carriers and noise in receive band is " -27 dBm at the ODU down

converter input.

( The sum of all carriers within 10 MHz from the desired is

" +30 dBc relative to

the desired carrier.

( The sum of all carriers is " +50 dBc relative to the desired carrier for operation at

64 ks/s and below, or

" +40 dBc at $ 64 ks/s operation.
