Keysight N9923-90001 User’s Guide179Data Analysis FeaturesAll about MarkersThere are more trace formats available th an marker formats. To display markerreadouts in more formats than are shown here, change the trace format, thenselect Default. Learn how to change format in “Format” on page 46.Searching with MarkersMarker Searches are used to move markers to locations on the trace whichexhibits the characteristics of the search criteria. Learn ‘What is a Peak” in“What Is a ‘Peak’” on page 182.How to Search with MarkersThe following menu structure applies to NA Mode. Keystrokes will be slightlydifferent for CAT, Pulse Measurements, and SA Modes.— Activate the marker to be used for the search (NOT necessary withBandwidth search.)— Thenpress Mrk ->/Tools.— Then Marker Search— Then choose one of the following:—Tracking ON OFF (NA Mode ONLY)——ON causes the active marker to se arch for the specified criteriawith each new sweep. Search criteria can include: Target,Bandwidth, Peak, Min. The searches begin with the first sweepafter Tracking is turned ON, based on the current search type.Trk appears next to the marker number.——OFF causes a new marker search only when the search featureis re-executed.—Peak Moves the active marker to the HIGHEST amplitude data point ofthe trace. Peak Excursion value is ignored. In SA Mode, the LOfeed-through signal (0 Hz) is also ignored.—Min (Not available in DTF) Moves the active marker to the LOWESTamplitude data point of the trace.—Target (NA Mode ONLY) Enter the Target value. The marker moves tothe first occurrence of the Target value to the right of its currentposition. The FieldFox interpolates between measured data points tofind the exact Target value to two decimal points. The interpolatedX-axis value is displayed in the marker readout or marker table.Subsequent presses of the Target softkey cause the marker to moveto the right to find the next occurrence of the Target value. When themarker reaches the end of the stimulus range, it “wraps around” andcontinues the search from the beginning of the stimulus range.
