UC-584 Universal Transponder Antenna Coupler VIAVI

UC-584 Universal Transponder Antenna Coupler VIAVI.A time-saving device that provides repeatable test results on the flight line or in the hangar.The UC-584 Universal Transponder Antenna Coupler solves the problem of reliable FAR Part 43 Appendix ‘F’ ERP (Effective Radiated Power) and transponder MTL (Minimum Trigger Level) testing in multi-path environments. The coupler mounts directlover the aircraft transponder antenna(s) and is secured in place with a toggle action grip,or slipped onto the top antenna when using the top mount
coupler.
 
The UC-584 provides 20 dB of isolation, ensuring airborne TCAS systems and air traffic controllers do not see UUT transponder altitude replies under test conditions. The innovative design of the UC-584 includes an integral positioning slot, ensuring a high level of measurement
repeatabilitis achieved, saving test time. The UC-584 can be connected to the VIAVI IFR6000, IFR6015, and APM-424 flight line test sets or to the VIAVI IFF-45TS direct-connect port, or to ansuitable transponder test set.
