The IFR / Aeroflex MLS-800 is microprocessor controlled bench test equipment designed to operate as a Ground Station Simulator. It provides the operator test capabilities to align and test airborne Microwave Landing System (MLS) receivers. The MLS-800 operational menu supports ICAO 1985 and ED-36A and EUROCAE ED-53A. The test equipment provides diagnostic test features for microwave landing system angle receivers. Test variables are selected via a 44-position keyboard and shown on test operational menus. The MLS-800 also supports complete main path simulation for approach (AZ), elevation (EL), high rate azimuth (HiAZ), back azimuth (BAZ) and flare (FL). Additionally, complete multi-path simulation capabilities include interference pulses and selectable fade rate modulation of 0.05, 1 and 1000 Hz.
