The Lisun EMI-9KC is a CISPR 16-1 compliant automatic EMI receiver covering 9 kHz to 1 GHz — the top of the EMI-9K range — supplied as a complete conducted and radiated emissions test system. The receiver integrates the attenuator internally and is housed in a fully enclosed, high-conductivity shielded structure to minimize self-EMI. It targets compliance testing of lighting luminaires, appliances, automotive electronics, IT and network equipment to CISPR 16-1, CISPR 15:2018, GB 17743, FCC and EN 55015, with radiated disturbance handled through the supplied CDNE-M316 coupling/decoupling network. The system ships with the LISN artificial mains network, CDNE-M316, isolation transformers and cables, and outputs an international-format report. Optional accessories include a pure-sine AC source, magnetic shielding cabinet, three-loop antenna, absorbing clamp and RF current probe.
