Output trigger signals are routed to the other radar functions such as the modulator, transmitter, receiver, and displays. Often the system must also provide triggers to ancillary equipment that operates in concert with it. Equipment, such as video mapper, requires radar triggers.

The radar video and the IFF replay must be properly placed to ensure accuracy. Civilian authorities use it as an aid in tracking aircraft.
