2.24.3.12 Detector 1
PSA Only: Allows you to set the detector to be used by the trace which will be used for
display purposes only.
The detector choices are:
•Normal − displays the peak of CW-like signals and maximums and minimums of
noise-like signals.
•Average − displays the average of the signal within the bucket. The averaging method
depends upon Avg Type selection (voltage, power or log scales).
•Peak − displays the maximum of the signal within the bucket.
•Sample − displays the instantaneous level of the signal at the center of the bucket
represented by each display point.
•Negative Peak − displays the minimum of the signal within the bucket.
•Quasi Peak − a fast-rise, slow-fall detector used in making CISPR compliant EMI
measurements.
•EMI Average − displays the instantaneous level of the signal at the center of the bucket,
just like the sample detector. Also changes the auto coupling of VBW, RBW and
Avg/VBW Type and the set of available RBWs. Used in making CISPR-compliant
measurements.
•EMI Peak − the same as the Peak detector but uses CISPR related bandwidths.
•MIL Peak − the same as the Peak detector but uses MIL related bandwidths.
