The parameters that can be set for FM are listed in the table below.

Frequency
deviation
The maximum value Δf of the instantaneous frequency deviation from
the carrier frequency fc, which corresponds to the maximum or
minimum value of the modulating waveform amplitude when the
frequency deviation is reached. The modulated carrier frequency varies
in the range fc ± Δf
When source is internal or channel, this value can be set directly.
When source is external, modulated by external. The full amplitude of
the external modulation waveform corresponds to the set frequency
deviation.
PM
PM is phase modulation, a modulation method that uses the amplitude of the modulating
waveform to control the instantaneous phase of the carrier.
The parameters that can be set for PM are listed in the table below.
