{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.
{Intelsat}
Allows the user to set the spectral shape of Tx Data
Filter.
{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 view the Symbol Rate.
{1/2 Rate VIT, 3/4 Rate VIT, 7/8 Rate VIT,
Optional encoders
1/2 Rate SEQ, 3/4 Rate SEQ , 7/8 Rate SEQ , 2/3 Rate
TRE (8PSK), 3/4 Rate Turbo (.793), 1/2 Rate Turbo
(.495), 1/3 Rate Turbo (.325), 3/4 Rate CSC}
Allows the user to select the Tx Code Rate and Type.
{ENABLED, DISABLED}
Allows the user to enable or disable the Differential
Encoder. Having the encoder enabled ensures proper
phase lock.
{RS, RS EF}
Allows the user to select the scrambler type.
{ENABLED, DISABLED}
Allows the user to enable or disable scrambler operation.
{1/15 (IBS), 1/15 (Async), 96 Kbps (IDR), None}
Used with IDR, IBS, or Asynchronous Interface Only.
Allows the user to select the framing type.
{INV. TERR&BASE, INV. BASEBAND, INV.TERR
DATA, NONE}
Allows the user to invert the Tx Data polarity.
{NONE, SWAPPED}
Allows the user to swap the I&Q Channels.
(BPSK Mode Only)
