ALT-8015 FMCW/Military Pulse Radio Altimeter Test Set (Discontinued)

Versatile time-saving portable test set for testing installed FMCW and military pulse radio altimeters

The ALT-8015 Radio Altimeter Flightline Test Set provides an easily configurable RF based altitude simulation to quickly test an installation, or direct connect to the Line Replaceable Unit (LRU) for additional troubleshooting capability. A large color touchscreen displays parametric measurements and allows for detailed profiles to be set up to emulate actual airborne conditions. For commercial applications, see the ALT-8000.

General - The user interface is Windows™ based and provides various pages for control of the test set and display of parametric measurements including: TX power, TX frequency (center), sweep rate, TX pulse width (pulse systems). 

Profiles - The Profile page allows the user to create, save, recall or delete named profiles. Each profile is comprised of individual legs. Start, stop altitudes and rates are definable for each leg. A profile can then be executed to simulate a complete landing approach including flare out or a take-off and departure. 

RF Coupling - 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. 

Setup - The setup page allows system, user and RF connection parameters to be set by the user, including RS-232, AID, RF cable loss and altitude offset.

The graphical user interface provides various screens for control of the test set and display of parametric measurements including: TX power, TX frequency (center), sweep rate, FM deviation, TX pulse width, and PRF (pulse systems)
