{NORMAL, INVERTED}
Allows the user to invert the direction of rotation for PSK
Modulation. Normal meets the IESS Specification.
{QPSK, BPSK, OQPSK, 8PSK, 16QAM}
Allows the user to select the modulation type.
{MIL-188-165A, INTELSAT 0.35, DVB SAT 0.35, DVB
SAT 0.25}
Allows the user to set the spectral shape of Tx Data
Filter.
{0 to 1 dB}
Allows the user to set the offset on the transmit output
power will will allows for some specific cable loss up to
1dB.
{Refer to Technical Specs for Data Rates}
Allows the user to set the Data Rate in bps steps via the
Front Panel Arrows or Keypad.

Allows the user to select the Tx Code Rate and Type.
{DISABLE, ENABLE}
Allows the user to disable or enable the TPC Interleaver.
Valid only on Radyne Turbo Codes TPC .495 and TPC
