    Note: older quantum composers pulse generators had a divide-by-n func- tion. The duty cycle mode is a more general case. To reproduce the divide- by-n function, set the on cycle to 1 and set the off cycle to (n-1), where n is the divide-by-n factor. To use the channel gating function each channel ma...
