3 VMA Mode
3.3 Monitor Spectrum Measurement
Peak
Because they may not find a spectral component's true peak, neither AVERage nor
SAMPle detectors measure amplitudes of CW signals as accurately as Peak or
NORMal, but they do measure noise without the biases of Peak detection.

Command
[:SENSe]:MONitor:DETector:TRACe[1]2|3 AVERage | NEGative | NORMal | POSitive
| SAMPle | RMS
[:SENSe]:MONitor:DETector:TRACe?
Example
:MON:DET:TRAC NORM
:MON:DET:TRAC?
:MON:DET RMS
Sets the detector to AVERage. AVERage uses RMS averaging, so this is equivalent to selecting RMS
Notes The query returns a string corresponding to the detector type as shown below
String Returned Definition
NORM
Normal
AVER
Average (RMS)
POS
Peak
SAMP
Sample
NEG
Negative Peak
The RMS selection sets the detector type to AVERage with RMS averaging. Therefore, if RMS has
been selected, the query returns “AVER”
Couplings When "Detector Select Auto/Man" on page 670 is ON, the detector selected depends on the Trace
(Average) type

Detector Select Auto/Man
Sets the Detector mode to Auto or Manual. In Auto, the proper detector is chosen
based on rules that take into account the measurement settings and other
instrument settings.
When any detector is selected by the user, this toggles automatically set to Man
(manual).
