AM Phase

Macro: AMmodPhase

Controls the phase of the Sine modulator, independent of the main wave (carrier) Phase. This is particularly useful if you have set AM Sync, and want to adjust the display start point relative to the modulator cycle.

If you set the modulator frequency to match the main frequency, the result is a wave at the main frequency but with strong 2nd harmonic distortion, plus a DC component. Changing the modulator phase allows you to change that DC component.

Macro Notes:

L.1.AMmodPhase=90 sets Left Stream 1 AM Modulator Phase to 90 degrees. Alternatively, AMmodPhase=>1 increments or AMmodPhase=>-1 decrements the current Modulator Phase by 1 degree. Only +/-1 degree steps are allowed with this command format.
