Testing RF Devices, Cables Used for Maintenance

Configuration Requirements for Emission Testing and Cables

Question: What are the configuration requirements for emission testing of an Equipment Under Test (EUT) when the cables, which are absent during normal operation and are connected only temporarily (for maintenance, initial installation, pre-programming, repair, adjustment etc..

Answer: ANSI Standard C63.4 – 2003, which is incorporated the FCC Rules by reference (47 CFR 15.31(a)(6) and 15.38), is the procedure the FCC uses for testing most intentional and unintentional radiators. Cables that are used only temporarily for maintenance, repair, adjustment, etc. need not be connected to the EUT during compliance testing. Cables that are used during normal operation, whether permanently connected or not, must be connected. (See Clause 6.2 of ANSI Standard C63.4-2003.)
