VIAVI/Aeroflex ALT-9000 Radio Altimeter Test Set
VIAVI/Aeroflex ALT-9000 Radio Altimeter Test Set is a portable radio altimeter flight line test set that utilizes fiber optic delay to allow it to work with all types of radio altimeters. The ALT-9000 tests the complete radio altimeter system, allowing the operator to isolate a problem to the antenna, coax, LRU or indicator. This eliminates unnecessary LRU swaps or other system component replacements.
The 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.
The graphical touch screen interface provides intuitive controls and display of parametric measurements including:
- TX Power
- TX Frequency*
- FM Deviation*
- Sweep Rate*
- Pulse Width*
- PRF*
