All about Markers
There are more trace formats available than marker formats. To display marker
readouts in more formats than are shown here, change the trace format, then

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

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
— Then press Mrk ->/Tools.
— Then
— Then choose one of the following:

Bandwidth search.)
Marker Search
—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 value is ignored. In SA Mode, the LO
feed-through signal (0 Hz) is also ignored.
—Min
(Not available in DTF) Moves the active marker to the LOWEST
amplitude data point of the trace.
—Target
(NA Mode 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 find the next occurrence of the Target value. When the
marker reaches the end of the stimulus range, it "wraps around" and
continues the search from the beginning of the stimulus range.
