Viterbi Rate Auto
When enabled, the L-Band adapter automatically establishes the
Viterbi Rate when acquiring Front End Lock.
NOTE. The Viterbi Rate Auto option will not work correctly if the
Viterbi rate is 5/6. If this rate (5/6) is known, or suspected, then
the Auto option should not be used.
22KHz Tone The Local Oscillator Frequency is selected by applying a 22 kHz
tone.
Invert Spectrum The sense of modulation may be inverted due to the number of
mixing stages in the installation. Enabling the Invert Spectrum
checkbox will invert the L-Band output.
Front End Lock If the L-Band adapter Front End is able to acquire full lock onto
the channel and is receiving the signal correctly, the Front End
Lock (FEL) indicator will light up green. When a signal is
present but no lock is achieved the indicator is red. When no
signal is found, the indicator is gray.
BER Bit Error Rate.
