activates automatic level control for RF output A.
Example:
SCPI conformUsage:
[:SOURce<hw>]:POWer[:LEVel][:IMMediate][:AMPLitude] <Amplitude>
The command sets the RF output level in CW mode. In addition to numerical values, it
is also possible to specify UP and DOWN. The level is then increased or decreased by the
value specified under [Source<[1]|2>:]POWer:STEP.
As with the Level value entered in the header, the OFFSet value is also taken into con-
sideration with this command.
The specified value range is therefore only effective if :SOURce:POWer:OFFSet is set
to 0. The value range for other OFFSet values can be calculated using the following
formula:
Minimum level + OFFSet ...Maximum level + OFFSet
The keywords of this command are largely optional. Therefore, both the long and short
form of the command are shown in the example.
Parameters:
float
Minimum level ... Maximum level
The value range for the level setting varies according to the
instrument model.
The value range depends on whether or not the instrument is
equipped with the option High Power.
The values are given in the data sheet.
