Conducting modulation measurement

The following sections describe how to conduct modulation analysis.

Constellation

The constellation is used to observe some aspects of modulation accuracy and can
reveal certain fault mechanisms such as I/Q amplitude imbalance or quadrature imbal-
ance. It displays constellation diagram by modulation types.
