The VIAVI ALT-9000 is a portable universal radio altimeter flight line test set designed to test and troubleshoot installed radio altimeter systems. It uses true RF time delay and path loss simulation to replicate real operating conditions for FMCW, pulse, Low Probability of Intercept (LPI), Combined Altitude Radar Altimeter (CARA), and next-generation systems. It helps maintenance teams isolate faults to antennas, coaxial cables, LRUs, or indicators—reducing unnecessary component replacements and downtime.
The price and features make it a very attractive option compared to similar altimeter test sets available on the market. Request a quote now.
