Marker Searches are used to move markers to locations on the trace which exhibits the

How to Search with Markers
The following menu structure applies to NA Mode. Keystrokes will be slightly different for CAT, Pulse
Measurements, and SA Modes.
1. Activate the marker to be used for the search (NOT necessary with Bandwidth search.)
2. Then press Mkr ->/Tools.
3. Then choose one of the following:
Tracking ON OFF
— ON causes the active marker to search for the specified criteria with each new
sweep. Search criteria can include: Target, Bandwidth, Peak, Min. The
searches begin with the first sweep after 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 feature is re-executed.
Peak
Moves the active marker to the HIGHEST amplitude data point of the trace. Peak
Excursion and Peak Threshold value is ignored. In SA Mode, the LO feed-through signal
(0 Hz) is also ignored.
Next Peak
Moves the active marker to the next highest amplitude data point of the
trace. Peak Excursion value is ignored.

Mkr -> RefLev
Minimum
(Not available in DTF, RTSA, SA, or I/Q Analyzer) Moves the active marker to
the LOWEST amplitude data point of the trace.
Min Search
(I/Q Analyzer, RTSA, and SA modes Only) Moves the active marker to the
LOWEST amplitude data point of the trace. If a marker is turned off, it is turned on
before the minimum search is performed.
Target
(NA Mode and Pulse Measurements ONLY) Enter the Target value. The marker
moves to the first occurrence of the Target value to the right of its current position. The
FieldFox interpolates between measured data points to find the exact Target value to
two decimal points. The interpolated X-axis value is displayed in the marker readout or
marker table. Subsequent presses of the Target softkey cause the marker to move to the
