6.16.3 (INFO) RX (Receive information)

6.16.4 (INFO) BUFF (Buffer information)

This displays if the buffer is enabled or disabled, shows the exact clocking mode
(Tx=Rx, or Tx<> Rx), and the buffer size. Pressing ENTER takes the user back to the
previous menu.

6.16.5 (INFO) FRAME (Framing and EDMAC information)

Rx:1140.000 5000.000 TUR
8P 0.95 D BUF +/-32k
The information displayed here is as follows:
Top line:
Receive Frequency and Data Rate (NOTE: Due to space limitations, the
resolution of displayed frequency is limited to 1 kHz, and data rate to 10Hz,)
FEC Decoder type (VIT = Viterbi, VRS=Viterbi + Reed-Solomon,
TCM = Trellis Coded + Reed-Solomon, TUR = Turbo, UNC = uncoded)
Bottom line:
Demodulation type (Q = QPSK, OQ= OQPSK, B = BPSK, 8P = 8-PSK,
Code Rate (Unc = Uncoded, 2144 = 21/44, then 5/16, 1/2, 2/3, 3/4, 7/8, 0.95)
Descrambler state (D = Descrambler on, N = Descrambler off)
Clocking Mode (SAT = buffer disabled, BUF = buffer enabled)
