To explicitly set the averaging method, use the Meas Setup, Average Type key. When you are using
average detection with the Power method is equivalent to what is sometimes referred to as “RMS
detection”. The detailed information about the different types of averaging is found in Average Type
in the Meas Setup key menu.
Key Path
Trace/Detector, Detector
Example
DET:TRAC3 AVER Sets the detector to average for trace 3.
Notes
For the specific case of a customer wanting RMS detection, they need to set the averaging type
to RMS, and also select average detection for the trace:
AVER:TYPE RMS
DET:TRAC AVER
Dependencies
Selecting any detector (even the currently selected detector) for a given trace turns Update and
Display on for that trace.
Couplings
Selecting a specific detector type turns “Auto” to false for this trace (manual).
Selecting a detector for a trace (pressing the key or sending a [:SENS]:DET:TRAC command) puts
Update On and Display On for that trace, even if that detector was already selected. Note that
the legacy command [:SENS]:DET[:FUNC] does NOT exhibit this behavior.
Selecting a detector, whether by pressing the softkey or sending the equivalent SCPI command,
will turn trace math to Off for the selected/specified trace.
The VBW filter is not used for this detector, so varying the VBW will have no effect for any
traces for which this detector is selected (other than to slow down the sweep, because of the
coupling to Sweep Time of VBW). If any traces are active for which VBW does not apply (traces
with Average, EMI Average, RMS Average or Quasi Peak detectors), then an * displays after the
VBW annotation on the front panel.
Use of the Average detector affects the VBW setting because of its effect on the VBW/RBW
coupling. See the BW section under the key “
”.

Peak
For each bucket (interval) in the trace, Peak detection displays the highest amplitude within the
bucket.
