:SENSe:BANDwidth:EMIFilter:STATe?
:SENSe:BWIDth:EMIFilter:STATe?
[:SENSe]:BANDwidth|BWIDth[:RESolution]
Syntax
[:SENSe]:BANDwidth|BWIDth[:RESolution] <freq>
[:SENSe]:BANDwidth|BWIDth[:RESolution]?
Description
Sets the resolution bandwidth (RBW).
Queries the resolution bandwidth.
Parameter
Name
Type
Range
Default
<freq>
Discrete
1 Hz to 10 MHz (at 1-3-10 step)
3 MHz
Remarks
The setting command is only available for GPSA mode. The query command is available for both the GPSA
and RTSA modes.
Return Format
In GPSA mode, the query returns the resolution bandwidth in scientific notation. Its unit is Hz.
In RTSA mode, the query returns the specific frequency resolution value of RBW1 through RBW6.
Example
The following command sets RBW to 1,000 Hz.
:SENSe:BANDwidth:RESolution 1000
:SENSe:BWIDth:RESolution 1000
The following query returns 1.000000000e+03.
:SENSe:BANDwidth:RESolution?
:SENSe:BWIDth:RESolution?
[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO
Syntax
[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO OFF|ON|0|1
[:SENSe]:BANDwidth|BWIDth[:RESolution]:AUTO?
Description
Enables or disables the auto setting mode of RBW.
Queries the status of the auto setting mode of RBW.
Parameter
Name
Type
Range
Default
——
Bool
OFF|ON|0|1
ON|1
Remarks
In auto mode, the resolution bandwidth changes with the span (non-zero span).
This command is only available for GPSA mode.
