Figure 7-3: Constellation diagram (64 QAM)
X-axis, Y-axis = amplitudes of the signal components, scaled to the peak envelope power; where minimum
scaled amplitude = -1, maximum scaled amplitude = +1
Application: To classify modulation.
Signal acquisition points: See Table 7-2.
Eye Diagram
The eye diagram displays synchronized and superimposed sections of either the in-
phase or the quadrature components of the signal.
Figure 7-4: Eye diagram with partially closed eye (QPSK)
X-axis = time in the range of -/+ 1 symbol
Y-axis = amplitude, scaled to the peak envelope power; where minimum scaled amplitude = -1, maximum
scaled amplitude = +1
