3.2.10.3 Detector
Lets you choose and configure detectors for the selected trace.
Detector
Selects a specific detector for the current measurement. The detector selected is
then applied to the selected trace.
The instrument is in Auto detection by default, and normally Auto detection will
choose the best detector for you automatically. If you choose a detector manually,
this will turn Auto detection off for the selected trace.
For the SCPI UI, two commands are provided. One is a legacy command, which
affects all traces. There is also a command which is new for the X-Series, which uses
a subopcode to specify to which trace the specified detector is to be applied.
The three detectors at the end of the Detector menu, Quasi Peak, EMI Average, and
RMS Average, are referred to collectively as the “CISPR detectors” because their
behaviors are specified by the CISPR 16–1–1 specification. These detectors appear
only if the N6141A or W6141A application or Option EMC installed and licensed.
NOTE
The instrument can typically provide 3 different detectors simultaneously.
Occasionally the instrument can only provide 2 simultaneous detectors, typically
when the Average detector is selected. When one of the CISPR detectors is
selected, it is only possible to have that one detector, so all active traces change
to that detector. It is never possible to have more than 3 simultaneous detectors.
