Phase Modulation (PM)
What the settings
are for
In the case of phase modulation the information is contained in the phase
changes to the output signal. The amplitude of the output signal stays
constant. The amplitude of the modulation signal is contained within the size
of the phase change (phase deviation) in the output signal. The frequency of
the modulation signal is contained in the frequency of the phase change in
the output signal.
You can use the PM MOD submenu to set the PM modulation signal,
modulation frequency and phase deviation.
