2 Conducted Disturbance Test (at Mains Terminal)
2.1 Test Instruments
Refer to Sec. 1.3 Test Instruments.
2.2 Test Arrangement and Procedure
Table-top Equipment
- The EUT was placed on a non-conductive table which was 80 cm above the horizontal coupling
plane. The rear of the EUT was 40 cm from the vertical coupling plane.
- The excess interface cables were folded at the cable center into a bundle no longer than 40 cm, so
that the bundles were on the table.
- The EUT was connected to the main power through a L.I.S.N. This set up provided 50 ohm / 50
H coupling impedance for the measuring equipment.
- All auxiliary equipment received power from a second L.I.S.N.
- The conducted emissions were measured between the Line Phase and the PE ground and
between the Neutral Phase and the PE ground using an EMI Receiver.
- The values were recorded.

3.1 Test Instruments
Refer to Sec. 1.2 Test Instruments.
3.2 Test Arrangement and Procedure
Table-top Equipment
- The EUT was placed 0.4 meters from the horizontal ground plane with EUT being connected to
the power mains through a line impedance stabilization network(LISN). All other support
equipments powered from additional LISN(s). The LISN provide 50 Ohm/50H of coupling
impedance for the measuring instrument.
- Interconnecting cables that hang closer than 40cm to the ground plane shall be folded back and
forth in the center forming a bundle no longer than 40cm.
- I/O cables that are not connected to a peripheral shall be bundled in the center. The end of the
cable may be terminated, if required, using the correct terminating impedance. The overall length
shall not exceed 1m.
- ISN at least 80cm from nearest part of EUT chassis.
- The communication function of EUT was executed and ISN was connected between EUT and
associated equipment and the ISN was connected directly to reference ground plane.
