CDN for USB Type B

CDN-USB-BE is part of a series of coupling/decoupling networks designed specifically for testing products for conducted immunity per IEC/EN 61000-4-6.

• Designed for conducted immunity testing of USB communication ports, compliant with IEC/EN 61000-4-6 and CISPR 16-1-2, enabling controlled RF disturbance coupling onto USB signal and power conductors.
• Operates over a frequency range of 150 kHz to 230 MHz, covering the full conducted RF immunity spectrum required by IEC/EN 61000-4-6.
• Intended for USB cables using a Type B connector on the EUT side and a Type A connector on the auxiliary equipment side, reflecting common real-world USB device-to-host configurations.
• Provides the standardized 150 Ω common-mode impedance across the specified frequency range, meeting the impedance requirements defined by IEC/EN 61000-4-6 and CISPR 16-1-2.
• Supports up to 40 V RF input voltage and 1 A maximum current, allowing stable injection of RF disturbance levels during immunity testing of USB interfaces.
• Equipped with a 50 Ω BNC RF input port, enabling direct connection to RF signal generators and power amplifiers used in conducted immunity test systems.
• Constructed with a rugged metal enclosure and an unpainted base surface to ensure effective grounding and consistent performance during immunity testing.
• Individually calibrated with NIST-traceable calibration data and a defined voltage division factor, supporting accurate, repeatable, and traceable establishment of test levels.
• Used to inject RF common-mode disturbances onto USB cables while maintaining uninterrupted data and power communication between auxiliary equipment (such as host PCs, test controllers, or USB hubs) and the EUT.
• Well suited for real-world immunity evaluation of USB Type B devices, including printers, laboratory instruments, industrial controllers, medical equipment, test and measurement devices, scanners, and embedded systems that rely on USB connectivity during operation.
• Allows manufacturers to confirm that USB ports remain functional under RF disturbance conditions, helping ensure reliable product performance in electrically noisy industrial and commercial environments.
• Integrates into complete conducted immunity test systems when used with Com-Power ADA-USB-BE shorting adapters, ADA-515-2 150 Ω to 50 Ω adapter sets, TEP-050 50 Ω terminator, appropriate attenuators or directional couplers, and Com-Power ACS series power amplifiers, providing a comprehensive solution for USB conducted immunity testing.
