:ALC:BANDwidth

[:SOURce]:POWer:ALC:BANDwidth|BWIDth <num>freq suffix]
[:SOURce]:POWer:ALC:BANDwidth|BWIDth?
This command overrides the signal generator's automatic ALC bandwidth
selection with the users specific selection. For waveforms with varying
amplitudes, high crest factors, or both, the recommended ALC loop bandwidth
is the low bandwidth setting of the generator. Limiting the loop bandwidth of
the ALC circuit will prevent the ALC from sampling the fast rising edges of
pulsed waveforms. A limited, or narrow bandwidth will result in a longer ALC
sample time and a more accurate representation of the signal's level.
Key Entry

:ALC:BANDwidth|BWIDth:AUTO

[:SOURce]:POWer:ALC:BANDwidth|BWIDth:AUTO ON|OFF|1|0
[:SOURce]:POWer:ALC:BANDwidth|BWIDth:AUTO?
This command turns the bandwidth (BW) auto state on or off.
The bandwidth auto function allows the signal generator to automatically
select a bandwidth for the automatic leveling control (ALC) circuit.

*RST 200 (2kHz when ALC:BAND:BWID is set to AUTO)
Auto
Remarks Use this command when the ALC state is set to On. This
command will override the automatic ALC bandwidth
selection set by the :ALC:BANDwidth|BWIDth:AUTO
command.
Supported All Models
ON (1) This choice allows the signal generator to automatically
select an ALC BW. The selection of the ALC BW
depends on the signal generator modulation type.
OFF (0) This choice disables automatic selection of the ALC BW.
