VIAVI ALT-9000 Radio Altimeter Test Set

The VIAVI ALT-9000 is a versatile, time-saving, portable aircraft radio altimeter test set - It utilizes fiber-optic delay to allow it to work with all types of radio altimeters.

This test unit tests the complete radio altimeter system, allowing the operator to isolate a problem with the antenna, coax, LRU, or indicator. This eliminates unnecessary LRU swaps or other system component replacements.

The VIAVI ALT-9000 provides altitude simulations with true RF time delay and path loss models to test any format of radio altimeter system including Low Probability of Intercept (LPI), Combined Altitude Radar Altimeter (CARA) & Next Generation variants.

All items required to test radio altimeter systems are included in the ALT-9000 kit.

Features

• Tests all types of radio altimeters, including LPI variants
• Direct connect at the UUT TX/RX connectors or the aircraft's TX/RX antennas via antenna couplers
• Fast detector for tracking LPI radio altimeters with TX power management
• Software upgradeable
• Parametric measurements of TX power/frequency/pulse width/FM deviation/PRF for most radio altimeter types
• Large touchscreen display

Benefits

• Perform complete closed-loop system tests
• Replicate in-flight conditions
• Isolate faulty components of the installed system
• Create profiles for dynamic altitude simulations
• Simulate 5 ft.* to 10,000 ft. in 5-ft. increments (Extended range option: Simulate 16,000 ft. and 25,000 ft. as discrete altitude selections)

Applications

• Simulate static or dynamic altitudes to support testing of TCAS and GPWS/TAWS aircraft systems
• Test RX sensitivity of the radio altimeter
