Constellation Display Mode
Selects the display presentation with the following horizontal menu choices:
Symbols – Only the samples at the optimal symbol decision times are display, as white dots. Correct
transmitter operation should group them tightly around the eight ideal phase points. See Figure 2.2.7.7-6.
Samples – In addition to the symbol points, samples between symbol times three times their number are
displayed as blue dots. See Figure 2.2.7.7-8.
Trajectories – Instead of sample points, blue lines connect adjacent samples to approximate the continuous
transmitter output throughout the burst. See Figure 2.2.7.7-8.
