54 Agilent N5181A/82A MXG Signal Generators SCPI Command Reference
Basic Function Commands
Power Subsystem ([:SOURce]:POWer)
:MODE
Supported All Models
[:SOURce]:POWer:MODE FIXed|LIST
[:SOURce]:POWer:MODE?
This command sets the signal generator power mode to fixed or swept.
FIXed This choice stops a power sweep, allowing the signal generator to operate at a
fixed power level. Refer to “[:LEVel][:IMMediate][:AMPLitude]” on page 57 for
setting the output power level.
LIST This choice selects the swept power mode. If sweep triggering is set to immediate
along with continuous sweep mode, executing the command starts the LIST or
STEP power sweep.
NOTE To perform a frequency and amplitude sweep, you must also select LIST as the frequency
mode. See “:FREQuency:MODE” on page 36 for selecting the list mode for a frequency sweep.

:PROTection:STATe
Supported All models
[:SOURce]:POWer:PROTection[:STATe] ON|OFF|1|0
[:SOURce]:POWer:PROTection[:STATe]?
This command enables or disables the power search protection function. The power search protection
function sets the attenuator to its maximum level whenever a power search is initiated. This can be
used to protect devices that are sensitive to high average power or high power changes. The trade off
on using the power protection function is decreased attenuator life, as the attenuator will switch to
its maximum setting during a power search.
NOTE Continual or excessive use of the power search protection function can decrease attenuator
life.
ON (1) Causes the attenuator to switch to and hold its maximum level setting during a
power search.
OFF (0) Sets the attenuator normal mode. The attenuator is not used during power search.
Example
:POW:PROT ON
The preceding example enables the power inhibit function.
