POS =Positive peak
SAMP =Sample
NEG =Negative peak
QPE =Quasi Peak
EAV =EMI Average
RAV =RMS Average
Dependencies
When Tune & Listen is turned on, or Demod Audio is the selected Analog Output:
•
all active traces are forced to use the same detector.
•
CISPR detectors (QPD, EMI Avg, RMS Avg) are unavailable
CISPR detectors are grayed out when you have manually selected FFT sweep. Conversely, if any
CISPR detector is selected on an active trace, the auto rules for sweep type will never select FFT,
and manual FFT selection will be grayed out.
When Signal ID is on, the Detector key is grayed out for Traces 2–6 in Image Supress mode and
for Traces 3–6 in Image Shift Mode.
If the grayed out key is pressed, an advisory message is generated. If the equivalent SCPI
command is sent, this same message is generated as part of a “–221, Settings conflict” warning.
It is never possible to have more than 3 simultaneous detectors, and sometimes fewer than
three. If the analyzer has to enforce this limit a message is generated, “Detector n changed due
to physical constraints” where “n” is the detector number.
Couplings
The auto detector rules depend upon marker type, averaging state and type, trace state writing
mode, and trace active state.
If the Avg Type is in Auto, and any of the CISPR detectors is selected on any active trace, the
Voltage Averaging type is auto-selected.
In Tracking Source mode, if a stepped source is used (for example, an external source using
option ESC), the best detector is Average, as this gives optimal sensitivity. Therefore, when
operating a source in Tracking Source mode, Auto selection is Average. All other detector
selections are allowed, but in most cases the user will want to stick with the Auto selection,
which gives optimal sensitivity.
Preset
Preset returns all traces to “auto”, which will result in Normal (Rosenfell) detection for all traces.
