Viavi ALT-8000

The ALT-8000 is the world’s first and only radio altimeter flight line test set. It weighs approximately 10 pounds with a large 12-inch color touch screen, making it easy to use. The ALT-8000 is a universal test set for 4.3 GHz FMCW (frequency modulated continuous carrier wave) radio altimeters and pulse radio altimeters. The simulator is also designed to be software upgradeable for military use as well as civil aviation applications.
The supplied antenna couplers allow the radio altitude system to be quickly verified without access being required to test ports on the UUT LRU. The RF looped test verifies TX frequency, power, sweep rate, and RF level control provides the means to test UUT sensitivity.

Unlike other testers, the ALT-8000 tests from the antenna to the indicator in the cockpit, allowing the operator to replicate in-flight conditions and isolate a bad component of the installed system.

• Tests FMCW radio altimeters including CDF types
• Tests pulse radio altimeters (non-pulse compression types)
• Direct-connect to UUT T/R or to installed system via antenna couplers
• Full RF loop test allows TX, RX, Antenna or Feeder faults to be identified
• Multi-channel operation (via additional test sets)
• Programmable multi-leg climb/descend profiles
• Large touch-screen display with simple user interface
• Remote control interface USB/LAN
• Lightweight and compact about 10 lbs. (4.5 kg)
• Battery 4 hours plus duration
