These screens display information on the current configuration of the unit. Depending on
the choice selected, one of the following screens will be displayed:

The information displayed here is as follows:
Top line:
Transmit Frequency and Data Rate (NOTE: Due to space limitations, the resolution of
displayed frequency is limited to 1 kHz, and data rate to 10 bps)
FEC Encoder type (VIT = Viterbi, VRS=Viterbi + Reed-Solomon,
TCM = Trellis Coded + Reed-Solomon, TUR = Turbo, UNC = uncoded)
Bottom line:
Modulation type (Q = QPSK, OQ= OQPSK, B = BPSK, 8P = 8-PSK, 8Q = 8QAM,
Code Rate (Unc = Uncoded, 2144 = 21/44, then 5/16, 1/2, 2/3, 3/4, 7/8, 0.95)
Scrambler state (S = Scrambler on, N = Scrambler off, I = IESS-315 On)
Clocking Mode (INT = internal, EXT = external, LOP = loop)
Output power level
Transmit output state (ON = on , OF = off,
EO= external off, RT= Rx-Tx Inhibit)
TSI state (I = Transmit Spectral Inversion on, N = off)
