Set Modulator Power
Offset
Command:
Response:
Status: Response:
MC MPO_snn.n'cr'
MPO_snn.n'cr''lf']
MC MPO_'cr' 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.
Set Modulator Output

Where: snnn.n = -40.0 to 0.0, in 0.1 steps (nominal
range in dBm).
Note: The nominal power range is modified relative to
the value specified by the modulator power offset
(MPO_).
