• Los
s
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.
The info field contains the following search results:
• Bandwidth is the n-dB bandwidth of the bandpass/bandstop region, where n is the selected x dB
Bandwidth. The bandwidth is equal to the difference between the Upper Bandwidth Edge (UBE)
and the Lower Bandwidth Edge (LBE).
• Center is the stimulus frequency where the trace reaches its absolute maximum (minimum) within
the bandpass (bandstop) region.
• Lower Band Edge is the closest frequency below the center frequency where the trace is equal to
the center value minus n dB.
• 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.

Marker Tracking
Causes the active minimum/maximum or target search of the active marker to be repeated after each
sweep: When tracking mode is active the marker typically changes its horizontal and its vertical position
as the measurement goes on.
Tracking mode properties
The tracking mode is available for all search modes, i.e. for minimum/maximum search, target search and
bandfilter search. The Marker Tracking function in the Search submenu is valid for an active
minimum/maximum and target search; bandfilter tracking can be activated separately. Tracking is marker-
specific but can be switched on for several markers simultaneously.
Switching between Max Search and Min Search does not affect the tracking mode.Tracking is switched off
though when one of the following actions is performed:
• Redefinition of the active marker position by means of the functions in the Marker menu or drag-
and-drop of the active marker symbol.
• Change of the active marker's search mode, e.g. from a minimum/maximum search to a target
search.
Tracking is a toggle function: Selecting the function repeatedly switches the tracking mode on and off.
