[:SENSe]:BANDwidth|BWIDth[:RESolution]
Syntax
[:SENSe]:BANDwidth|BWIDth[:RESolution] <freq>
[:SENSe]:BANDwidth|BWIDth[:RESolution]?
Description
Sets the resolution bandwidth (RBW) of the meter frequency.
Queries the resolution bandwidth of the meter frequency.
Parameter
Name
Type
Range
Default
<freq>
Discrete
100 Hz to 10 MHz (at 1-3-10 step)
120 kHz
Remarks
When the EMC measurement standard is "None" and "Gauss" filter is selected, the RBW range is as above.
When "EMI" filter is selected, resolution bandwidth can only be 200 Hz, 9 kHz, 120 kHz, or 1 MHz.
Return Format
The query returns the resolution bandwidth in scientific notation. Its unit is Hz.
Example
The following command sets RBW to 1000 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 the meter RBW.
Queries the status of the auto setting mode of the meter RBW.
Parameter
Name
Type
Range
Default
--
Bool
OFF|ON|0|1
ON|1
Remarks
OFF: indicates "Manual" mode. You can use the [:SENSe]:BANDwidth|BWIDth[:RESolution] command to
set the RBW value.
ON: indicates "Auto" mode. The RBW automatically couple to the frequency of the meter.
