Modulator Configuration Commands

Modulator
Frequency

Command:
Response:

Status:
Response:

>add/MF_nnnnn.nnnn'cr'
RF_OFF'cr''lf']
>add/MF_nnnnn.nnnn'cr''lf']

Where: nnnnn.nnnn = Frequency in MHz, 950.0000 to
1750.0000 in 100 Hz steps for non-terminal frequency
display.

For terminal frequency mode, the range will be
determined by the LO frequency and high/low Mix of the
ODU.

Note: When the modulator frequency is programmed, the
RF output is switched off.

RF Output

Command:
Response:
Status:
Response:

>add/RF_xxx'cr''lf']
>add/RF_xxx'cr''lf']

Where: xxx = ON or OFF.

Response:

>add/AMRx_nnnn_mmmm.mmm'cr''lf']

>add/AMRx_nnnn_mmmm.mmm'cr''lf']

Where:

x = A, B, C, D, or V [preset designator].
nnnn = 1/2 (QPSK ½ Turbo and non-Turbo), [coder
rate], 3/4 (QPSK 3/4 Turbo and non-Turbo), 7/8
(QPSK 7/8), BP12 (BPSK ½), 8P23 (8PSK 2/3), OQ12
(OQPSK 1/2Turbo and non-Turbo), OQ34 (OQPSK
3/4 Turbo and non-Turbo), OQ78 (OQPSK 7/8), BPSK
(BPSK1/1 Turbo and non-Turbo), QPSK (QPSK 1/1
Turbo and non-Turbo), OQSK (OQPSK 1/1 Turbo,
and non-Turbo), 2144 (BPSK 21/44 Turbo Only),
B516 (BPSK 5/16 Turbo Only), and 8P34 (8PSK 3/4
Turbo Only).

mmmm.mmm = Data rate in kHz.

Burst Mode = nnnn= 1/2
mmmm.nnn = 19.2 or 57.6 kbps

Modulator

Command:
Response:


Status:

>add/SMRx_'cr'
RF_OFF'cr''lf']

See MR command.

Where: x = A, B, C, D, or V (preset designator).
Note: Setting the modulator rate turns off the RF
transmitter.
