VIAVI TC 201 TCAS

The VIAVI TC-201 TCAS/Transponder Directional Antenna Couplers are designed for reliable and repeatable testing of directional TCAS and combined TCAS/transponder antennas in avionics maintenance environments. The coupler shields the RF signal during testing, helping minimize interference with air traffic control and nearby aircraft while enabling accurate maintenance testing in the airborne condition.

When used with compatible VIAVI flight line test sets such as the IFR6000, IFR6015 or APM-424(V)5, the TC-201 supports TCAS, transponder and ADS-B performance testing, including testing in challenging high-multipath environments. Its directional design allows four-quadrant testing by simply rotating the bearing selector dial, while providing TCAS bearing accuracy of less than 10 degrees.

Features:

• Supports both phase and amplitude type TCAS antennas
• Suitable for TCAS, transponder and ADS-B performance testing
• Provides more than 20 dB of RF isolation
• Enables reliable ERP and MTL testing in high-multipath environments
• Shields RF signals to help reduce interference with air traffic control and nearby aircraft
• Adjustable lower antenna support pole
• Four-quadrant testing via a rotating bearing selector dial
• TCAS bearing accuracy of less than 10 degrees
• Designed for use with compatible VIAVI avionics flight line test sets
• Enables repeatable measurements and helps reduce test time
• Eliminates the need for direct line-of-sight to the antenna under test
• Supports maintenance testing without requiring DD-1494 frequency authorization in applicable test scenarios
