The objective of EMI Conducted tests is to define the amplitude of current Ic and Voltage Vc emission from the Device Under Test (DUT) onto the power mains or to define the immunity of the DUT to the conducted interference.
The mains lines themselves do not allow for reliable EMI measurements since their impedance is subject to marked variations that generates different test results at different test sites.
The PMM Artificial Mains Networks are LISN used for RFI measurements on AC three-phase, power supplied electric and electronic equipment usable from DC to 60 Hz.
The LISNs are three line V-network with an equivalent circuit of 50 ohm // (5ohm + 50μH), fully compliant with CISPR publ. 16, VDE 0876 and FCC part 15 regulation.
The LISNs are suited to perform measurements on conducted interference in the frequency range from 9 kHz to 30 MHz.
Designed according to criteria of cheaply and compactness they can be used together with PMM Systems for Conducted Interference or any other RF receiver.
The PMM LISNs are provided with a standard industrial power sockets, with a pilot conductor connector provided.
According to EN 60309 (IEC 309) Normative the pilot conductor can be used to operate a remote control switch, to avoid any mains connector operation with high current load.
