R&S FSQ Remote Control – Description of Commands
6.16.4 SENSe:DETector Subsystem
SENSe 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).
[SENSe:]DETector[:FUNCtion] APEak | NEGative | POSitive | SAMPle | RMS | AVERage
| QPEak
This command selects the detector for the data acquisition of the selected trace and 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.
• The RMS detector evaluates the root mean square at each sweep point.
• The AVERage detector evaluates the linear average power at each sweep point.
• 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 quasipeak detector can fully settle at each
measurement point.
The numeric suffix at DETector selects the trace to apply the detector to.
Example: "DET POS"
'Sets the detector in screen A to "positive peak".
Characteristics: *RST value: APEak
SCPI: conform
Mode: A
[SENSe:]DETector[: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: conform
Mode: A
