To Use Polar Markers - Agilent Technologies 89410A Operator's Manual

Analyzing Digitally Demodulated Signals (Options AYA and AYH)

To use polar markers

This task shows you how to select the polar-marker format (magnitude and
phase or real and imaginary) and polar-marker units (dBm, Watts, or volts).
This task is a continuation of the previous task.

Time points/symbol
The vector diagram shows all time points on the trajectories between
decision points. More points per symbol creates a smoother vector
diagram. If you want to examine the marker value only at the decision
points you may select a constellation diagram. The cross-hairs show the
ideal detection-decision points (for details, see online help for [
