3.3.Test Procedure
The EUT was placed on a non-metallic table, 80cm above the ground plane. The EUT Power
Via PC connected to the power mains through a line impedance stabilization network
(V-LISN). This provides a 50 ohm coupling impedance for the EUT (Please refer the block
diagram of the test setup and photographs). The AC line are checked to find out the
maximum conducted emission. In order to find the maximum emission levels, the relative
positions of equipment and all of the interface cables shall be changed according to ANSI
C63.10: 2013 on Conducted Emission Test.
The bandwidth of test receiver (R & S ESR7) is set at 9kHz.
The frequency range from 150kHz to 30MHz is checked.

Note 1: The product is powered by DC 12V and is shipped without an adapter, so the
conduction is exempt from testing
