depends on marker functions, trace functions, and trace averaging functions for the
current measurement.
The following options are available:
AUTO
The detector selected depends on marker functions, trace functions, average type,
and the trace averaging function
In the ACP measurement, when in AUTO, the detector selected is set to AVERage,
unless the Radio Standard defaults state otherwise e.g., it is set to Peak for Radio
Standard = PDC when Device = both MS and BTS, and when Radio Standard =
NADC and Device = MS
NORMal
The detector determines the peak of the CW-like signals, and it yields alternating
maximums and minimums of noise-like signals. This is also referred to as Rosenfell
detection
AVERage
The detector determines the average of the signal within the sweep points, using
RMS averaging
POSitive
Peak
The detector determines the maximum of the signal within the sweep points
SAMPle
The detector indicates the instantaneous level of the signal at the center of the
sweep points represented by each display point
NEGative
Peak
The detector determines the minimum of the signal within the sweep points
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.

[: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
