Basic Function Commands
Power Subsystem ([:SOURce]:POWer)
:ALC:SEARch:SPAN:STOP
Supported All Models
[:SOURce]:POWer:ALC:SEARch:SPAN:STOP <value><units>
[:SOURce]:POWer:ALC:SEARch:SPAN:STOP?
This command sets the stop frequency for a span power search over a user specified range.
The stop frequency has no default value. The stop frequency value will be the last value set before
powering off the instrument.
Key Entry Stop Frequency
:ALC:SEARch:SPAN:TYPE
Supported All Models
[:SOURce]:POWer:ALC:SEARch:SPAN:TYPE FULL|USER
[:SOURce]:POWer:ALC:SEARch:SPAN:TYPE?
This command enables you to select the frequency range for a span power search. You can specify
the range (USER) or you can select the full range (FULL) of the signal generator.
Key Entry Span Type User Full
:ALC:SEARch:SPAN[:STATe]
Supported All Models
[:SOURce]:POWer:ALC:SEARch:SPAN[:STATe] ON|OFF|1|0
[:SOURce]:POWer:ALC:SEARch:SPAN[:STATe]?
This command enables (1) or disables (0) the span mode, allowing you to perform power searches
over a selected range of frequencies. The power search corrections are then stored and used
whenever the signal generator is tuned within the selected range.
Key Entry Span
:ALC:SOURce
Supported All Models
[:SOURce]:POWer:ALC:SOURce INTernal|DIODe
[:SOURce]:POWer:ALC:SOURce?
This command enables you to select an automatic level control (ALC) source. You can select the
internal ALC source, an external detector source, or a millimeter–wave source module. Refer to the
User’s Guide for more information on ALC leveling, bandwidth, and the power search function.
Example
:POW:ALC:SOUR DIOD
The preceding example selects an external detector as the source (the unit must be connected to the
signal generator).
