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.

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.

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

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.

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.

Where: snn.n = -30.0 to –5.0, in 0.1 steps (nominal range in
dBm).
Notes:
2.
The nominal power range is modified relative to the
value specified by the modulator power offset
(MPO_).
2.
The MOP_ command will return status only when
local AUPC is enabled.
