A radio frequency (RF) control system including a RF generator having a power amplifier that outputs a RF signal and a controller. A matching network receives the RF signal and generates a plurality of RF output signals. The matching network includes a ratio tuning element to vary a ratio of power between the plurality of RF output signals. The first controller communicates a ratio control signal to the matching network, and the matching network controls the ratio tuning element in accordance with the ratio control signal. The RF controls system operates in a continuous and pulse mode of operation. The controller can also control the rise or fall of a pulse edge or a level or duration of incremental changes in the pulse edge.
