Parameter Type Protocol Description
Modulator
Frequency Command:
Response:
Status:
Response: >add/MF_nnn.nnnnnn'cr'
RF_OFF'cr''lf']
>add/MF_nnn.nnnnnn'cr''lf'] Where: nnn.nnnnnn = Frequency in MHz, 50.000000 to
180.000000 in 1 Hz steps.
Note: When the modulator frequency is programmed, the RF
output is switched off.
RF Output
(IF Output) Command:
Response:
Status:
Response: >add/RF_xxx'cr''lf']
>add/RF_xxx'cr''lf'] Where: xxx = ON or OFF.
Modulator
Rate Preset
Assignment Command:
Response:
Status:
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 1/2), [coder rate], 3/4 (QPSK 3/4), 7/8 (QPSK
7/8), BP12 (BPSK 1/2), 8P23 (8PSK 2/3), OQ12 (OQPSK 1/2),
OQ34 (OQPSK 3/4), and
OQ78 (OQPSK 7/8).
mmmm.mmm = Data rate in kHz.
Modulator
Rate Preset
Selection 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.

Assignment
and
Selection Command:
Response:
Status:
>add/SMRV_nnnn_mmmm.mmm'cr'
RF_OFF'cr''lf']
See MR command.
Where: mmmm.mmm = Data rate in kHz.
nnnn = 1/2 (QPSK 1/2), [coder rate], 3/4 (QPSK 3/4), 7/8 (QPSK
7/8), BP12 (BPSK 1/2), 8P23 (8PSK 2/3), OQ12 (OQPSK 1/2),
OQ34 (OQPSK 3/4), and
OQ78 (OQPSK 7/8).
Note: Setting the modulator turns off the RF transmitter.
Set
Modulator
Power Offset Command:
Response:
Status:
Response: >add/MPO_snn.n’cr’’lf’]
>add/MPO_snn.n’cr’’lf’] Where: snn.n = +99.0 to –99.0, in 0.1 dB increments.
Note: The modulator power offset is added to the nominal power
level to adjust the transmit power range.

Modulator
Output
Power Level Command:
Response:
Status:
Response: >add/MOP_snn.n’cr’’lf’]
>add/MOP_snn.n’cr’’lf’]
Where: snn.n = -30.0 to –5.0, in 0.1 steps (nominal range in
dBm).
Notes: The nominal power range is modified relative to the value
specified by the modulator power offset (MPO_).
The MOP_ command will return status only when local
AUPC is enabled.
Scrambler
Enable Command:
Response:
Status:
Response: >add/SE_xxx’cr’’lf’]
>add/SE_xxx’cr’’lf’]
Where: xxx = ON or OFF.
