• Upper Band Edge is the closest frequency above the center frequency where the trace is equal
to the center value minus n dB.
• The Quality Factor is the ratio between the Center frequency and the 3-dB Bandwidth; it does
not depend on the selected x dB Bandwidth.
• Loss is the loss of the filter at its center frequency and is equal to the response value of marker
no. 4. For an ideal bandpass filter the loss is zero (0 dB), for an ideal bandstop filter it is –
dB.

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 Ref to Max, 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 Bandfilter Tracking –
Bandstop Search Ref to Marker.

The Marker Functions use the active marker to define the sweep range, scale the diagram and
introduce an electrical length offset.
