Enable or disable carrier modulation
IF Carrier Frequency
Enter any value in float or real format. Example: for 720 MHz, type 7.2e+8 or
720000000.
Input of the MDU

X DGU (s): Merge of X DGUs

F. Input: Format Input (external source)
Bit Rate or Symbol Rate expressed in bps or Bauds.
Independent rates can be defined for I and Q in UQPSK.
Telemetry PCM Coding technique:

NRZ-L/M/S: Non Return to Zero

DNRZ

BPL/M/S: Bi-Phase

NRZM Merge
Type of DNRZ Code (only in QPSK or in OQPSK)
In UQPSK:
Ratio between I Channel and Q Channel in dB
Type of Modulation: BPSK, QPSK, OQPSK, UQPSK, 8PSK, GMSK, 16QAM,
16APSK, 32APSK, 64APSK, SCCC or DVB-S2
Select Gray X or Natural X in 8PSK
