Bandfilter Tab
"Bandfilter" search allows you to search for trace segments with a bandpass or band-
stop shape, and determine characteristic filter parameters.
Background information
Refer to
Bandfilter for arbitrary scalar traces
"Bandfilter" search can be used for a broad range of measured quantities (see
on page 241). To obtain real filter parameters, the trace format
must be "dB Mag", the measured quantity must be a transmission S-parameter and a
frequency sweep must be performed. However, for other formats, measured quantities
or sweep types, the "Bandfilter" functions can still be useful to analyze general trace
properties.
The "Eval Range..." button opens the "Evaluation Range" dialog that allows you to nar-
row the "Bandfilter" search to a particular stimulus range. See
.
Bandwidth
Specifies the minimum excursion of the bandpass and bandstop peaks.
●
A bandpass peak must fall off on both sides by the specified <Bandwidth> value to
be considered a valid peak.
●
A bandstop peak must be <Bandwidth> below the maximum level in the search
range (bandpass value) to be considered a valid peak.
