The MLS-801 ramp test set provides go/no-go verification of the Microwave Landing System angle receiver installed in an aircraft.

The test set generates a single channel signal that includes all necessary AM and DPSK modulation for testing of the azimuth, elevation, back azimuth and clearance functions as well as all basic data words in their standard test conditions.

• Rugged construction, meets MIL-T-28800D, Type 2, Class 2, Style A requirements
• Automatic Test Sequence mode to allow one person operation
• Control Motion Deflection Position to test auto-pilot coupling
• Complete simulation of the MLS transmission cycle, including all angular information as well as data words
• Built-In-Test (BIT) for confidence testing and fault isolation of the test set
• Azimuth, High Rate Azimuth and Back Azimuth offset approach simulation of up to 40 degrees
• Fixed transmission frequency, set to the FAA specified channel (500)
