![VIAVI - ALT-8000 FMCW/Pulse Radio Altimeter Flightline Test Set VIAVI - ALT-8000 FMCW/Pulse Radio Altimeter Flightline Test Set](/sites/default/files/styles/max_650x650/public/1alt8000.jpg?itok=OyMZ1UC5)
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.
