CDN for USB Type A

CDN-USB-AE Coupling Decoupling Network is designed to test products that use USB cables for communication.

• Designed for conducted immunity testing of USB communication ports, fully compliant with IEC/EN 61000-4-6 and CISPR 16-1-2, enabling controlled RF disturbance coupling onto USB signal and power lines.
• Operates over a frequency range of 150 kHz to 230 MHz, covering the full conducted RF immunity spectrum specified by IEC/EN 61000-4-6.
• Specifically intended for USB cables, featuring a USB Type A connector on the EUT side and a USB Type B connector on the auxiliary equipment side, matching common laboratory and product test configurations.
• Provides the standardized 150 Ω common-mode impedance across the test 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 conducted immunity testing of USB interfaces.
• Equipped with a 50 Ω BNC RF input port, enabling direct connection to RF signal sources and power amplifiers used in conducted immunity test systems.
• Constructed with a durable metal enclosure and an unpainted base surface to ensure effective grounding and repeatable performance during immunity testing.
• Supplied with individual NIST-traceable calibration, including a specified voltage division factor, supporting accurate, repeatable, and traceable setup of immunity 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.
• Ideal for real-world immunity evaluation of USB-enabled products, including industrial controllers, medical devices, instrumentation, consumer electronics, printers, scanners, measurement equipment, and embedded systems that rely on USB connectivity during operation.
• Enables manufacturers to verify that USB ports remain functional under RF disturbance conditions, ensuring compliance and reliable performance in electrically noisy environments.
• Integrates into complete conducted immunity test systems when used with Com-Power ADA-USB-AE 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, forming a comprehensive solution for USB conducted immunity testing.
