Pulse B Level

Controls: Gen Dlg >> Stream >> Wave >> Pulse >> B Level
Macros: PulseBlevel, PulseMir

Similar to Pulse A Level. However, since it is often desired to have the positive and negative pulses of a biphasic pair mirror each other, there is a special 'Mir' (Mirror) button to the left of the A and B Level buttons. When this is active, the B Level will be grayed out; any changes to A Level will cause the actual B Level value to be the negative of the A Level.

Setting the B Level to 0 (or to the 0 Level value) will give what appears to be a single monophasic pulse, but this is usually not the best way to do that. It's better to set B Width to 0, so that A Width will give complete control over the duty cycle. However, there may be occasions where you want to deliberately limit the range of duty cycles, and for that you can set B Level to 0 and use B Width to set the minimum Off (baseline dwell) time.

Macro Notes:

L.1.PulseBlevel=50 sets the Left Stream 1 Pulse B Level to 50%.

L.1.PulseMir=1 sets Left Stream 1 Pulse Level to Mirror. L.1.PulseMir=0 cancels it, and L.1.PulseMir=x toggles Mirror 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.
