CDNEs for CISPR15/16 testing – 3 Core Cable Emissions
CDNEs are based on the CDN as specified in IEC61000-4-6 (Conducted RF Immunity test). In this test, the CDN is used for the coupling of RF onto a cable. In principle, the CDN can be used in reverse, ie coupling any RF on the cable out to an analyser. In an earlier version of EN 55015, these CDNs were specified as suitable for measuring emissions. However, the current version of the standard specifies a CDNE which is essentially a CDN refined to deliver higher accuracy particularly at higher frequencies.
The CDNE M3 is designed for 3 core cable. For 2 core cable see our CDNE M2.

Compliance
The these CDNEs are 100% compliant with the specifications detailed in CISPR15, ed 9, CISPR16-1-2 and CISPR16-2-1. Frequency range is 30MHz to 300MHz
Safety
These CDNEs are fitted with shrouded 4mm safety connectors, easy to connect and entirely safe.
Integrity
These CDNEs offer direct connection from the cable under test to the receiver/analyser. They avoid all the uncertainties related to the use of OATS. Measurements are consistent and repeatable.
