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.

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) for the non TX L-Band modem and –40.0 to 0.0,
in 0.1 steps for the TX L-Band modem.
Notes:
1. 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.
