About Marker Search

Description

Searches the measurement data with the current BandwidthTarget (default is -3). To continually track the filter bandwidth, use BandwidthTracking.

This feature uses bandwidth markers 1-4 to determine the bandwidth, center frequency, loss, and Q factor (Center Freq / Bandwidth). If not already, they are activated. To turn off these markers, either turn them off individually or DeleteAllMarkers.

The bandwidth statistics are displayed on the analyzer screen. To get the bandwidth statistics, use either GetFilterStatistics or FilterBW, FilterCF , FilterLoss ,or FilterQ.

The analyzer screen will show either Bandwidth statistics OR Trace statistics; not both.

To search a UserRange with the bandwidth search, first activate marker 1 and set the desired UserRange. Then send the SearchFilterBandwidth command. The user range used with bandwidth search only applies to marker 1 searching for the max value. The other markers may fall outside the user range.
