PM / Slope / PWM Dialog

For convenience, this dialog includes duplicates of the main carrier phase and frequency controls that are also in the Tone Freq dialog, plus controls to select the modulator source and modulation depth, as well as to set the frequency and phase of the dedicated sine source if that is selected.

This is actually a multi-purpose dialog, which changes to fit the Wave type and certain Wave settings. The Ramp Wave dialog allows you to select normal Phase modulation or Slope modulation, and Pulse Wave allows Phase or Width modulation.

This is not an available option for noise-type waves, or for Arb or Play waves where the Step Timing option has been selected.

See also Phase / Slope / Width Modulation, Stream Modulation, Waveform Stream Controls.
