CDN for RJ-45 Shielded Com-Power CDN-T8SE
I Introducing CDN-T8SE:
The CDN-T8SE is used to conduct emissions or immunity testing on devices with shielded (or screened) transmission lines with up to four balanced pairs. It is used when the signal/telecommunications ports for the EUT and AE ports of the CDN-T8SE are equipped with protected RJ45 sockets. The RF input/output port is located at the top of the network and is equipped with a female BNC type connector. The outer surface of the network.
