Searching with Markers
Marker Searches are used to move markers to locations on the trace which exhibits the
characteristics of the search criteria. Learn ‘What is a Peak” in
“What Is a ‘Peak’” on page 457
.
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.
— Activate the marker to be used for the search (NOT necessary with Bandwidth search.)
— Then press
Mkr ->/Tools
.
— Then choose one of the following:
—
Tracking ON OFF
(NA Mode ONLY)
——
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 -> Center
Moves the current active selected marker to the center frequency for the
current frequency range displayed.
—
Mkr -> RefLev
Moves the current active marker to the acquisition.
—
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 right to
