coupling decoupling networks

CDN for RJ-45 Shielded

  • The CDN-T8SE is suitable for conducted emissions and immunity tests on signal/telecom ports (such as ethernet) intended for connection to shielded (Cat. 3 or Cat. 5) lines containing up to four balanced pairs.
  • The CDN-T8SE could be referred to as a “dual-threat” network, as it can be used either as a CDN for conducted immunity testing per IEC 61000-4-6, or as an ISN for conducted emissions testing per CISPR 22/32.
  • It meets all applicable requirements of these standards for each test, as well as those contained within CISPR 16-1-2.
  • The CDN-T8SE is individually calibrated for all necessary performance parameters with NIST traceability. The calibration data and certifi cate is shipped with each network. Recognized ISO 17025 accredited calibration is also available upon request.
