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, I/Q Analyzer, NA, NF, RTSA, SA, and Pulse Measurements Modes.
