3.6. Test Procedure

The EUT was placed on a non-metallic table, 80cm above the ground plane. The EUT Power

connected to the power mains through a line impedance stabilization network (L.I.S.N. 1#). The

other peripheral devices power cord connected to the power mains through a line impedance

stabilization network (L.I.S.N. #2), this provided a 50-ohm coupling impedance for the EUT

(Please refer to the block diagram of the test setup and photographs). Both sides of power line

were checked for maximum conducted interference. In order to find the maximum emission, the

relative positions of equipments and all of the interface cables were changed according to ANSI

C63.4-2003 on conducted Emission test.

The bandwidth of test receiver (R&S TEST RECEIVER ESCI) is set at 10kHz.

The frequency range from 150kHz to 30MHz is checked. The test result are reported on Section

3.7.

3.7. Conducted Disturbance at Mains Terminals Test Results

PASS. (All emissions not reported below are too low against the prescribed limits.)

The EUT with the following test mode was tested and read QP values and average values, the

test results are listed in next pages.

4.5.2.Turn on the power of all equipment.

4.5.3.Let the EUT work in test mode (Data Transmitting) and test it.

4.6. Test Procedure

The EUT was placed on a non-metallic table, 80 cm above the ground plane inside a

semi-anechoic chamber. An antenna was located 3m from the EUT on an adjustable mast. A

pre-scan was first performed in order to find prominent radiated emissions. For final emissions

measurements at each frequency of interest, the EUT were rotated and the antenna height was

varied between 1m and 4m in order to maximize the emission. Measurements in both horizontal

and vertical polarities were made and the data was recorded. In order to find the maximum

emission, the relative positions of equipments and all of the interface cables were changed

according to ANSI C63.4-2003 on Radiated Emission test.

The bandwidth setting on the test receiver (ROHDE&SCHWARZ TEST RECEIVER ESCI) is

120 kHz.

The resolution bandwidth of the Agilent Spectrum Analyzer E4446A was set at 1MHz. (For

above 1GHz)

The frequency range from 30MHz to 1000MHz was pre-scanned with a peak detector and all

final readings of measurement from Test Receiver are Quasi-Peak values.

The frequency range from 1GHz to 5GHz was checked with peak and average detector,

measurement distance is 3m in 3m chamber.

Finally, selected operating situations at Anechoic Chamber measurement, all the test results are

listed in section 4.7.

For frequency range 30MHz~1000MHz

The EUT with the following test mode was tested and read QP values and average values, the

test results are listed in next pages.

Temperature: 25℃ Humidity: 55%

The details of test mode is as follows：

No. Test Mode

1 Data Transmitting

For frequency range 1GHz~5GHz

The highest frequency of the internal sources of the EUT is less than 108 MHz, the measurement

shall only be made up to 1 GHz. So the frequency rang 1GHz-5GHz radiation test not

applicable.
