A radar system having a transmit signal path and a receive signal path and an event generator which is responsive to command signals provided by a digital signal processor (DSP) is described. The DSP generates command signals and provides the command signals to the event generator. In response to the command signals, the event generator generates event signals in the radar system. The event signals include but are not limited to ramp control signals provided to a controllable signal source which provide RF signals to the transmit path of the radar.
