CDN for 8 Line (4 Balanced Pairs)
- Designed for conducted immunity testing in accordance with IEC/EN 61000-4-6 and CISPR 16-1-2, enabling controlled RF coupling onto four balanced unscreened conductor pairs commonly used in Ethernet and multi-pair communication interfaces.
- Covers a frequency range of 150 kHz to 230 MHz, supporting the full conducted RF immunity spectrum required by international EMC immunity standards.
- Intended for cables with four unscreened balanced pairs, making it suitable for systems that use a standard Ethernet (RJ45) connector, where all four balanced pairs must be tested simultaneously.
- Implements the specified 150 Ω common-mode impedance across the test band, ensuring compliance with impedance profiles defined by IEC/EN 61000-4-6 and CISPR 16-1-2.
- Supports up to 40 V RF input voltage and 1.5 A continuous current, allowing stable application of conducted immunity test levels while protecting the EUT and auxiliary equipment.
- Equipped with RJ45 connectors for both EUT and auxiliary equipment connections and a 50 Ω BNC RF input, enabling direct connection of Ethernet-based devices without modifying the cable or connector.
- Provides verified common-mode decoupling performance, isolating auxiliary equipment from injected RF disturbances while maintaining uninterrupted data communication during immunity testing.
- Supplied with individual calibration and a defined voltage division factor, ensuring accurate, repeatable, and traceable establishment of calibrated drive levels.
- Used to inject RF common-mode disturbances across all four balanced pairs of an Ethernet cable simultaneously, ensuring realistic immunity evaluation of devices that rely on full Ethernet connectivity during operation.
- Ideal for testing Ethernet-enabled products such as industrial controllers, network switches, routers, IP cameras, PLCs, gateways, and automation equipment that must remain operational while exposed to conducted RF disturbances.
- Enables manufacturers to verify conducted immunity performance of any product using a 4-pair balanced Ethernet interface, including PoE-powered devices, networked sensors, and communication-intensive industrial systems.
- Integrates into complete conducted immunity test systems when used with Com-Power ADA-T4/T8 shorting adapters, ADA-515-2 150 Ω to 50 Ω adapter sets, TEP-050 50 Ω terminator, appropriate attenuators or couplers, and Com-Power ACS series power amplifiers.
