MOST150 E-O Converter Duplex

Part Number: B10472


The MOST150 E-O Converter Duplex is a set of two devices assisting in isolating a MOST150 coax DUT operating on MOST150 Coax Full Duplex physical layer during a functional EMC/ESD network test by converting the electrical MOST physical layer into an optical physical layer network and vice versa.

One MOST150 E-O Converter device is connected electrically to the MOST network devices outside of the EMC test chamber (this MOST150 E-O Converter is connected to a power supply and automatically charges the rechargeable batteries that are assembled inside) while the other MOST150 E-O Converter is connected electrically to the MOST network DUT inside the chamber. The network is completed when an optical connection is made between the two MOST150 E-O Converters.

With that setup the Full Blown EMC/ESD tests can be performed against the DUT while another device that is not fully EMC robust can be operated outside the EMC test chamber.
