Psophometric Testing

The railway electromagnetic enviroment is known to be one of the most severe in which to use telecommunications equipment. Test equipment using psophometric filtering is used to ensure equipment conforms to the Network Rail standard BR 13422 (Code of Practice for Immunisation of Signal & Telecommunication Equipment Against 25KV 50Hz Interference) and also ITU 041.

Charterhouse Solutions has considerable experience in working with the railway industry to provide small, portable and robust psophometric testing equipment for use at the trackside.
