Monitors the state of the demodulator.

{000 – 999 000 – 999 000 – 999 000 -
999}
Displays the demodulator signal-to-noise
ratio for each channel. Divide each
number by 10 to get the dB value (i.e. 355
= 35.5 dB).

{000 – 655 000 – 655 000 – 655 000 -
655}
Displays a relative indication of the AGC
level of each channel. Optimum
performance is approximately 320 – 420.
The lower the number, the higher the IF
signal.

Monitors the aggregate input level in dBm.

Monitor channels 1 and 2 input levels in
dBm.

Monitor channels 3 and 4 input levels in
dBm.

Displays channel 1 pre FEC BER.

Displays channel 1 post FEC BER.

Displays channel 2 pre FEC BER.

Displays channel 2 post FEC BER.

Displays channel 3 pre FEC BER.

Displays channel 3 post FEC BER.

Displays channel 4 pre FEC BER.

Displays channel 4 post FEC BER.
