Search (Bandpass or Bandstop) / Search Mode
Enables a bandpass or bandstop search (left/right icon) for an arbitrary search mode.
The search modes have the following effect:
●
"Ref to Max": The bandpass (bandstop) is the tallest (lowest peak) in the search
range. For a detailed description, refer to
●
"Ref to Marker": The bandpass (bandstop) is the tallest (lowest) peak in the search
range. The response value for the lower and upper band edges is calculated as the
response value at the active marker position plus (minus) the
. To be
valid, the peak must be above (below) the response value for the band edges.
●
"Absolute Level:" The bandpass (bandstop) is the tallest (lowest) peak in the
search range. To be valid, the peak must be above (below) -"Bandwidth". The
Lower Band Edge and Upper Band Edge values are given by the frequencies
where the trace is equal to -"Bandwidth".
●
"None": "Bandfilter" search switched off, result off.
Remote command:
CALCulate<Chn>:MARKer<Mk>:FUNCtion:BWIDth:MODE
Tracking
Causes the active "Bandfilter" search to be repeated after each sweep: When tracking
mode is active, the markers typically change their horizontal and vertical positions as
the measurement proceeds.
Tracking mode properties
Tracking modes are available for all search modes. The tracking modes for minimum/
maximum/peak search and target search are coupled; tracking for "Bandfilter" search
can be activated separately. Tracking is activated automatically when one of the "Band-
filter" search modes is selected.
Remote command:
"Bandfilter" tracking and marker/target search tracking are controlled with the same
command:
CALCulate<Chn>:MARKer<Mk>:SEARch:TRACking
