Bandpass Search Ref to Marker

Activates the search for a bandpass region on the active trace and activates bandfilter

Tracking

, starting at

the position of the active marker. A bandpass region is the closest peak in the search range with a

minimum excursion specified by means of the

x dB Bandwidth

parameter.

In contrast to a

Bandpass Search,

the

Bandpass Search Ref to Marker

does not change the position of

the active markers. The band filter search results are displayed in the bandfilter info field.

To search for a bandstop region in the vicinity of the active marker, use
