2.3 TEST PERFORMED
Conducted emissions were invested over the frequency range from 0.15MHz to 30MHz
using a receiver which bandwidth is set at 9KHz.
Radiated emissions were invested over the frequency range from 30MHz to 1000MHz
using a receiver which bandwidth is set at 120KHz. Radiated measurement was performed
at distance that from an antenna to EUT is 10meters.
2.4 APPENDIX
Appendix A: Measurement Procedure for Main Power Port Conducted Emissions
The measurements are performed in a Global lab’s room; The EUT was placed on
non-conductive 1.0m x 1.5m table, which is 0.8 meters above an earth-grounded.
Power to the EUT was provided through the LISN which has the Impedance
(50ohm/50uH) vs. Frequency Characteristic in accordance with the standard. Power to the
LISNs were filtered to eliminate ambient signal interference and these filters were bonded to
the ground plane. Peripheral equipment required to provide a functional system (support
equipment) for EUT testing was powered from the second LISN through a ganged, metal
power outlet box which is bonded to the ground plane at the LISN.
If the EUT is supplied with a flexible power cord, the power cord length in excess of the
distance separating the EUT from the LISN shall be folded back and forth at the center of the
lead so as to form a bundle not exceeding 40cm in length. If the EUT is provided with a
permanently coiled power cord, bundling of the cord is not required. If the EUT is supplied
without a power cord, the EUT shall be connected to the LISN by a power cord of the type
specified by the manufacturer which shall not be longer than 1 meter. The excess power cord
shall be bundled as described above. If a non-flexible power cord is provided with the EUT, it
shall be cut to the length necessary to attach the EUT to the LISN and shall not be bundled.
The interconnecting cables were arranged and moved to get the maximum measurement.
Both the line of power cord, hot and neutral, were measured.
