Phase Modulation (PM)
A modulated waveform consists of a carrier waveform and a modulating
waveform. The following figure shows an example of a PM waveform. PM is very
similar to FM, but in PM, the phase of the modulated waveform is varied by the
instantaneous voltage of the modulating waveform. The variation in phase of the
modulated waveform from the carrier waveform is called the phase deviation.

To Select PM
The U2761A allows only one modulation mode to be enabled at a time. The
U2761A does not allow PM to be enabled at the same time that sweep is enabled.
