T-47NC and T-47NH Multifunction Ramp Test Set is a battery-powered portable unit used to test the operation of Transponders and Interrogators including Mode S Transponders, TCAS Interrogators, and TACAN/DME equipment that are installed in aircraft and other vehicles. Tests of both Transponders and Interrogators can be performed by using the T-47NC/NH directional antenna to radiate to and from the unit-under-test (UUT) or by directly connecting to the UUT antenna port.
