The ALT-9000 from VIAVI Solutions is a Radio Altimeter Flight Line Test Set that operates from 4.2 to 4.4 GHz. It is a portable test set that utilizes fiber-optic delay to allow it to work with all types of radio altimeters. This instrument tests the complete RADALT system, which allows the operator to isolate a problem to the antenna, coaxial cable, line-replaceable unit (LRU) or indicator, eliminating unnecessary swaps or replacements of system components. The test set performs complete closed-loop system tests, replicates in-flight conditions, and creates profiles for dynamic altitude simulations. The comprehensive, efficient and user-friendly test process enables more frequent testing of flight systems, reducing the cost of take-off failures.
The ALT-9000 is battery operated and requires a DC supply of 11-32 V and consumes less than 75 W. This test set can be controlled via a touch-screen interface that also displays parametric measurements like Tx power, Tx frequency, FM deviation, sweep rate, pulse width PRF etc. It is available in a case that measures 21.6 x 47.5 x 41.7 cm with 2x TNC connectors.
