All about Markers
Markers move along the X-axis range of the measurement trace to provide a
numerical readout of each measured data point. Markers also allow you to search
for specific Y-axis values.
A trace can contain up to six markers.
The marker readout on the FieldFox screen displays X and Y-axis information for
the current active marker ONLY.
A Marker Table can be displayed that allows you to simultaneously view X and Y-
axis information for all markers.
Markers can be used in
CAT
,
NA
,
SA
, and
Pulse Measurements
Modes.
