The MLS-800 is a microprocessor controlled Ground Station Simulator designed to operate from a bench test environment. Test parameters are selected via a 44-position keyboard and displayed on test operational menus.

• Test Operational Menu supports ICAO 1985 and EUROCAE ED-53A and ED-36A
• Complete Main Path Simulation:
  • Approach (AZ) and High Rate Azimuth (HiAZ)
  • Elevation (EL)
  • Back Azimuth (BAZ)
  • Flare (FL)
• Complete Multi-path (MP) Simulation Capability:
  • Interference Pulses
  • Selectable Fade Rate Modulation of 0.05, 1 and 1000 Hz
• Control of all Beam Parameters:
  • Angular Position
  • Beam Amplitude Referenced to the Preamble
  • Norm and Half Width Pulse
  • Selectable Beam Width at 0.5°, 1°, 2°, 3°,4° or 5°
• Sync Capability for:
  • External Monitoring
  • Designating PFE and CMN Function
  • Designating Multi-path Function
• Preamble Parity, Symmetry and Percent Update
• Simulates all Basic Data Words plus Auxiliary Data Words with Parity Selection
• Full Range of MLS Channels
