2.4. Configuration of EUT on Measurement The following equipments are installed on Power Line Conducted Emission Measurement to

meet the commission requirement and operating regulations in a manner, which tends to

maximize its emission characteristics in a normal application.

EUT : Shenzhen Yihexin Technology Co., Ltd.

Model Number : B22

2.5. Operating Condition of EUT 2.5.1. Setup the EUT and simulator as shown as Section 2.2.

2.5.2. Turn on the power of all equipment.

2.5.3. Let the EUT work in test mode (Normal) and measure it.

2.6. Test Procedure The EUT system is connected to the power mains through a line impedance stabilization

network (L.I.S.N.). This provides 50ohm-coupling impedance for the EUT system. Please refer

the block diagram of the test setup and photographs. Both sides of 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

FCC/ANSI C63.4-2009 on Conducted Emission Measurement.

The bandwidth of test receiver (R & S ESCI 3) is set at 9KHz.

The frequency range from 150KHz to 30MHz is checked.

The test result is reported on Section 2.7.

3.5. Operating Condition of EUT 3.5.1.Setup the EUT as shown in Section 3.2.

3.5.2.Let the EUT work in test mode (Normal) and measure it.

3.6. Test Procedure EUT and its simulators are placed on a turntable, which is 0.8 meter high above ground. The

turntable can rotate 360 degrees to determine the position of the maximum emission level. EUT

is set 3.0 meters away from the receiving antenna, which is mounted on an antenna tower. The

antenna can be moved up and down between 1.0 meter and 4 meters to find out the maximum

emission level. Broadband antenna (calibrated bilog antenna) is used as receiving antenna.

Both horizontal and vertical polarization of the antenna is set on measurement. In order to find

the maximum emission levels, all of the interface cables must be manipulated according to

ANSI C63.4-2009 on radiated emission measurement.

The bandwidth of the EMI test receiver (R&S ESCI 3) is set at 120KHz.

The frequency range from 30MHz to 1000MHz is investigated.
