ALT-8000 RF-Based Portable Radio Altimeter Flightline Test Set

Aeroflex's ALT-8000 is the world's first RF-based portable radio altimeter flightline test set. It only weighs about 10 lbs (4.5 kg) 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 upgradable.

Features include:

• 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

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.

Multi-Channel Operation
Up to three test sets may be linked via an altitude sync line for executing 2 or 3 channel coordinated altitude simulations for auto-land system testing.

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.
