RAVerage: indicates the RMS average.
AVERage: indicates the voltage average.
NEGative: indicates the negative peak.
OFF: indicates disabling the detector.
By default, the detector 1 type is positive peak; the detector 2 type is quasi peak; the detector 3 type is
CISPR average.
Return Format
The query returns POS, QPE, CAV, RAV, AVER, NEG, or OFF.
Example
The following command sets the detector type of Detector 1 in the final measurement to POSitive.
:SENSe:FSCan:FINal:DETector1 POSitive
The following query returns POS.
:SENSe:FSCan:FINal:DETector1?
[:SENSe]:FSCan:FINal:DETector<n>:DWELl

Remarks
By default, the detector 1 dwell time is 200 ms; the detector 2 dwell time is 1 s; the detector 3 dwell time is
1 s.
The maximum dwell time is 60 s, and the minimum value depends on the detector type.
When the quasi peak detector is selected, the minimum dwell time is 0.5 ms. When the CISPR average or
RMS average detector is selected, the minimum dwell time is 0.1 ms. When the positive peak or negative
peak detector is selected, the minimum dwell time is depends on the smallest RBW among ranges turned
on in the scan table.

Return Format
The query returns the dwell time in scientific notation. The unit is s.
Example
The following command sets the dwell time of Detector 1 in the final measurement to 0.1 s.
:SENSe:FSCan:FINal:DETector1:DWELl 0.1
The following query returns 1.000000000e-01.
:SENSe:FSCan:FINal:DETector1:DWELl?
