2.2.3.4

Interleaver (Reed-Solomon Codec)

Depth 8 (Closed Network, ASYNC).

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

(TX)

2.2.4.1 Transmit

Frequency

The operator can select the center frequency of the output spectrum from 14.0 to 14.5
GHz, in 100 Hz steps.

2.2.4.2 Transmit

Frequency

Reference

The standard internal reference frequency has a stability-over-temperature of

% 0.001 PPM.

2.2.4.3 Phase

Noise

Note: RMS phase deviation and output signal to noise ration will be met at all times, at all
frequencies, at all temperatures, and at all power levels.

1. The maximum RMS phase deviation due to spurs and noise integrated from

100 Hz to 1 MHz is less than 3.0

&.

2. The Output Signal to Noise Ratio is

# 50 dB for all output power levels.

2.2.4.4

Transmit Output Switch

When set to OFF, no signal present at the wave-guide flange is greater than -30 dBm,
measured in a 3 kHz bandwidth.
