SENSe:DETector Subsystem
The SENSe:DETector subsystem controls the acquisition of measurement data via the selection of the
detector for the corresponding trace. The measurement windows are selected by SENSe1 (screen A)
and SENSe2 (screen B).

This command switches on the detector for the data acquisition in the selected trace and the
indicated measurement window.
• The APEak detector (AutoPeak) displays the positive and also the negative peak value of the
noise floor. If a signal is detected, only the positive peak value is displayed.
• The POSitive or NEGative detector only displays the positive or the negative peak value.
• With the Sample detector the value measured at the sampling time is displayed, whereas the
RMS value of the power measured at each test point is displayed with the RMS detector.
• The AVERage detector displays the power average value at each test point.
• The "CAVerage" detector represents the average value weighted with a time constant. This
detector is not available in the analyzer mode.
• The QPEak detector performs a signal evaluation for EMC measurements.
If QPEak is selected, the video filter is automatically switched off. The couplings between span and
RBW as well as between RBW and sweep time are also switched off and restored on selecting
another detector. A long sweep time should be selected so that the quasi-peak detector can fully
settle at each test point.
The trace is indicated as numeric suffix in DETector.
Example: "DET POS" 'Sets the detector in screen A to "positive peak".
Characteristics: *RST value: APEak
SCPI: conforming
Mode: A
[SENSe<1|2>:]DETector<1 to 3>[:FUNCtion]:AUTO ON | OFF
This command either couples the detector in the selected measurement window to the current trace
setting or turns coupling off. The trace is selected by the numeric suffix at DETector.
Example: "DET:AUTO OFF"
Characteristics: *RST value: ON
SCPI: conforming
Mode: A
