Occupied Bandwidth Measurement
Trace/Detector
Auto
When the detector choice is Auto, the analyzer selects the detector. The selected detector depends on
marker functions, trace functions, and trace averaging functions for the current measurement.
Notes: When you manually select a detector (instead of selecting Auto), that detector
is used regardless of other analyzer settings.
The detector choices are:
The Normal detector determines the peak of CW-like signals, and it yields
alternating maximums and minimums of noise-like signals. This is also
referred to as Rosenfell detection.
The Average detector determines the average of the signal within the sweep
points. The averaging method is Power Average (RMS).
The Peak detector determines the maximum of the signal within the sweep
points.
The Sample detector indicates the instantaneous level of the signal at the
center of the sweep points represented by each display point.
The Negative Peak detector determines the minimum of the signal within the
sweep points.
Couplings: When Detector setting is “Auto” ([:SENSe]:OBWidth:DETector:AUTO?),
Detector ([:SENSe]:OBWidth:DETector[:FUNCtion]?) switches aligning
with the switch of this parameter: “NORMal” with Clear Write, “AVERage”
with AVERage, “POSitive (peak)” with MAXHold, and “NEGative (peak)”
with MINHold.
