3.3 Instrument subsystem command
42
[:SOURce]:POWer:ALC:SEARch <Mode>
Function:
This command activates or deactivates the internal amplitude auto search of the signal
generator when ALC loop is turned on. Amplitude search will enable amplitude to
stabilize the signal generator on the output amplitude selected by users and keep the
internal modulator in drive state when ALC Loop is turned off. For ALC loop state, see
the command ―
:POWer:ALC[:STATe]
‖.
Setting format:
[:SOURce]:POWer:ALC:SEARch ON|OFF|1|0|ONCE
Query format:
[:SOURce]:POWer:ALC:SEARch?
Parameter:
<Mode> Discrete data. Auto amplitude search state is as follows:
OFF | 0: This command terminates Auto mode, and Search Style is Manual.
ON | 1: Amplitude is automatically searched with the change of RF output amplitude or
frequency. Search Style is then in Auto mode
ONCE Do Search once at current RF output frequency.
Example:
:POWer:ALC:SEARch 1 Search Style is Auto.
Reset status:
Manual

[:SOURce]:POWer:ALC:SOURce <Mode>
Function:
This command allows users to select ALC Level Control for the signal generator as
appropriate, including INT, EXT and Source Module.
Setting format:
[:SOURce]:POWer:ALC:SOURce INTernal|DIODe
Query format:
[:SOURce]:POWer:ALC:SOURce?
Parameter:
<State > Discrete data. Level Control is as follows:
INTernal
：
Level Control is INT,
DIODe external diode detector level control,
Example:
:POWer:ALC:SEARch:REFerence INT Level Control is INT.

[:SOURce]:POWer:ALC:SOURce:EXTernal:COUPling <CouplingValue>
Function:
This command sets EXT Detector Couple. When Level Control is EXT diode detector,
this command enables you to set the coupling value for external level control. For level
control, see the command ―
:POWer:ALC:SOURce
‖.
Setting format:
[:SOURce]:POWer:ALC:SOURce:EXTernal:COUPling <value>
Query format:
[:SOURce]:POWer:ALC:SOURce:EXTernal:COUPling?
Parameter:
<CouplingValue> EXT Detector Couple
Range: 16dBm[-90dBm
，
+90dBm].
Example:
:POWer:ALC:SOURce:EXTernal:COUPling 16dBm Ext Detector Couple is 16dBm.
Reset status:
16.00dBm
