4.3 Waveform Graphics
Each channel’s waveform graphics display provides a real
-time visual representation o
f the received signal’s
constellation, or eye pattern in the case for PCM/FM.
An example of a PCM/FM eye pattern is shown in Figure 13. An example of an SOQPSK constellation is shown in
Figure 14. Additional information about waveform graphics displays, including spectrum displays, is located in
section 4.4.2.28.
Figure 13: Example PCM/FM Eye Pattern
Figure 14: Example SOQPSK Constellation
In addition to the eye pattern or constellation, the waveform graphics screen displays signal strength and signal
quality in vertical bar graph form, a red line AGC Zero On indicator in the Signal Strength bar, and signal lock
detect through a padlock icon, as shown in Figure 15.
