IFR4000/6000 End of Manufacture


Since the early 2000’s, the IFR4000 and IFR6000 have been supporting global maintenance testing needs for multiple airborne systems. These test sets have reached the end of their life cycle paving the way for a new comprehensive all-in-one test solution, the VIAVI AVX-10K Communication, Navigation, and Surveillance Flight Line Test Set, in April of 2021.

VIAVI understand it takes time and a coordinated effort to replace equipment identified in an aircraft’s AMM or test procedures. Therefore, we want to ensure you have ample time, information, and support to make these changes. VIAVI would be happy to support redlining of existing procedures to accommodate AVX-10K operation in place of current referenced test equipment.
