Range
Default
<n>
Discrete
1|2|3|4|5|6|7|8|9|10
3|4|5
<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 for the specified range in scientific notation. Its unit is Hz.
Example
The following command sets RBW for Range 1 to 1000 Hz.
:SENSe:FSCan:SCAN1:BANDwidth:RESolution 1000
The following query returns 1.000000000e+03.
:SENSe:FSCan:SCAN1:BANDwidth:RESolution?
[:SENSe]:FSCan:SCAN<n>:BANDwidth[:RESolution]:AUTO
Syntax
[:SENSe]:FSCan:SCAN<n>:BANDwidth[:RESolution]:AUTO ON|OFF|1|0
[:SENSe]:FSCan:SCAN<n>:BANDwidth[:RESolution]:AUTO?
Description
Enables or disables the auto setting mode of RBW for the specified range.
Queries the status of the auto setting mode of RBW for the specified range.

ON|1
Remarks
In auto mode, the resolution bandwidth changes with the span.
Return Format
The query returns 0 or 1.
Example
The following command enables the auto setting mode of RBW for Range 1.
:SENSe:FSCan:SCAN1:BANDwidth:RESolution:AUTO ON
or :SENSe:FSCan:SCAN1:BANDwidth:RESolution:AUTO 1
The following query returns 1.
:SENSe:FSCan:SCAN1:BANDwidth:RESolution:AUTO?
