Trace/Detector
More Information
The available detectors are:
The Sample detector indicates the instantaneous level of the signal at the center of the bucket represented
by each display point.
The Normal detector determines the peak of CW-like signals, and it yields alternating maximums and
minimums of noise-like signals. This is also referred to as Rosenfell detection.
The Average detector determines the average of the signal within the bucket. The averaging method
depends upon Average Type selection (voltage, power or log scales).
The Peak detector determines the maximum of the signal within the bucket.
The Negative Peak detector determines the minimum of the signal within the bucket.
Notes: This is a SCPI only legacy command to preserve the classic functionality
wherein all traces are affected when a detector is selected.
The query returns a name that corresponds to the detector type as shown
below, and indicates the setting for Trace 1.
The RMS selection sets the detector type to AVERage and the Average Type
to RMS. Therefore if RMS has been selected, the query will return the
“AVER” string.
The EPOS selection sets the detector type to Peak and the EMI Standard to
CISPR. A query will then return POS
The MPOS selection sets the detector type to Peak and the EMI Standard to
MIL Impulse. A query will then return POS
The RAV parameter is not included in the command because this is not a
legacy detector; nonetheless, if it happens to be the detector on Trace 1 then
RAV is returned.
