Pulse B Width

Controls: Gen Dlg >> Stream >> Wave >> Pulse >> B Width
Macros: PulseBwidth, PulseTrk

Similar to Pulse A Width. However, since it is often desired to have the two widths of a biphasic pulse track each other, there is also a separate 'Trk' (Track) button situated vertically at the left of the two width buttons. When this is active, the B Width will be grayed out; any changes made to the A Width will automatically be made to the B Width.

If you want to create a monophasic pulse, you would typically set B Width to 0. This gives a rectangular wave with variable duty cycle, level, and offset.

Macro Notes:

L.1.PulseBwidth=10 sets the Left Stream 1 Pulse B Width to 10 units. Depending on the Width Units setting, this may be percent, degrees, samples, or seconds.

Note that the actual value set may be limited due to the period of the current Tone Frequency. For example, you can't set a pulse width of 10 seconds unless the frequency is less than 0.100 Hz.

L.1.PulseTrk=1 sets Track mode for Left Stream 1 Pulse Width. L.1.PulseTrk=0 cancels it and L.1.PulseTrk=x toggles Track mode off and on.

Note that setting Pulse values directly via macro does not automatically set the Wave to Pulse. Use Wave=Pulse to do that.
