NOTE1-The lower limit shall apply at the transition frequencies. NOTE2-The limit decreases linearly with the logarithm of the frequency in the range 0.15MHz to 0.50MHz.
4.4.EUT Configuration on Measurement
The following equipments are installed on Conducted Emission Measurement to meet EN55014–1 requirements and operating in a manner, which tends to maximize its emission characteristics in a normal application.
4.5.3. Let the EUT work in test mode then measure it.
4.6.Test Procedure
The EUT is put on the plane 0.8m high above the ground by insulating support and connected to the AC mains through Line Impedance Stability Network (L.I.S.N). This provided a 50ohm coupling impedance for the tested equipments. Both sides of AC line are investigated to find out the maximum conducted emission according to the EN55014 regulations during conducted emission measurement. The bandwidth of the field strength meter (R&S Test Receiver ESCS30) is set at 9kHz in 150kHz-30MHz and 200Hz in 9kHz-150kHz. The frequency range from 150kHz to 30MHz is investigated for AC mains.
4.7.Measuring Results
PASS. The frequency range 150 kHz to 30MHz is investigated.
Note: Emissions attenuated more than 20 dB below the permissible value are not reported.
The spectral diagrams are shown in the following pages.

5.4.3. Let the EUT work in test mode then measure it.
5.5.Test Procedure
The EUT is placed on the plane 0.8m high above the ground by insulating support and away from other metallic surface at least 0.4m. It is connected to the power mains through an extension cord of 6m min. The absorber clamp clamps the cord and moves from the far end to the EUT to measure the disturbing energy emitted from the cord. The bandwidth of the test receiver (R&S ESCS30) is set at 120KHz.
5.6.Measuring Results
PASS. The frequency range from 30MHz to 300MHz is investigated. Note: Emissions attenuated more than 20 dB below the permissible value are not reported. The spectral diagrams are shown in the following pages. Remark: All emission readings from the equipment under test are lower than the applicable limits (Table a) reduced by the margin (Table b)

The EUT is placed on a turntable, which is 0.8 meter high above the ground. The turntable can rotate 360 degrees to determine the position of the maximum emission level. The EUT is set 3 meters away from the receiving antenna, which is mounted on an antenna tower. The antenna can be moved up and down from 1 to 4 meters to find out the maximum emission level. Bilog antenna (calibrated by Dipole Antenna) is used as a receiving antenna. Both horizontal and vertical polarizations of the antenna are set on test. The bandwidth of the Receiver (ESCS30) is set at 120kHz.
6.5.Measuring Results
N/A.
6.5.1.Mains operated appliances
The EUT shall be also deemed to comply with the requirement of this standard in the frequency range from 300 MHz to 1 000 MHz without further testing if both conditions 1) and 2) below are fulfilled:
1). the disturbance power emission from the EUT is lower than the limits of Table 7 reduced by the values of Table 8; 2). the maximum clock frequency is less than 30 MHz After testing and evaluation, the product meets both requirements, so the radiation of this mode does not need to be tested.
6.5.2.Battery operated appliances
The EUT shall comply with the limits in Table 9 for the frequency range from 30 MHz to 1 000 MHz (see also Figure 5).
Note: Battery power is not supported, so this test is not required.

11.5.Test Procedure
The EUT are placed on a table, which is 0.8 meter high above the ground. The EUT is set 3 meters away from the transmitting antenna, which is mounted on an antenna tower. Both horizontal and vertical polarizations of the antenna are set on test. Each of the four sides of the EUT must be faced this transmitting antenna and measured individually. In order to judge the EUT performance, a CCD camera is used to monitor its screen. All the scanning conditions are as following: Condition of Test Remark ---------------------------------------------- --------------------------------------- 1. Fielded Strength 2. Radiated Signal 3. Scanning Frequency 4. Sweep time of radiated 5. Dwell Time
3V/m (Severity Level 2) Unmodulated 80-1000MHz 0.0015 Decade/s 1 Sec.

12.4.3.Let the EUT work in test mode then measure it.
12.5.Test Procedure
The EUT is put on the table, which is 0.8 meter high above the ground. This reference ground plane shall project beyond the EUT by at least 0.1m on all sides and the minimum distance between EUT and all other conductive structure, except the ground plane beneath the EUT, shall be more than 0.5m.
12.5.1.For input and output AC power ports:
The EUT is connected to the power mains by using a coupling device, which couples the EFT interference signal to AC power lines. Both polarities of the test voltage should be applied during compliance test and the duration of the test is 2 mins.
12.5.2.For signal lines and control lines ports:
It’s unnecessary to test.
12.5.3.For DC output line ports:
It’s unnecessary to test.
12.6.Test Result

13.4.3.Let the EUT work in test mode then measure it.
13.5.Test Procedure
1) Set up the EUT and test generator as shown on Section 13.1.2. 2) For line to line coupling mode, provide a 1.0 KV 1.2/50us voltage surge (at
open-circuit condition) and 8/20us current surge to EUT selected points. 3) At least 5 positive and 5 negative (polarity) tests with a maximum 1/min
repetition rate are conducted during test. 4) Different phase angles are done individually. 5) Record the EUT operating situation during compliance test and decide the
EUT immunity criterion for above each test.

14.4.3.Let the EUT work in test mode then measure it.
14.5.Test Procedure
14.5.1.For AC Mains
1) Set up the EUT, CDN and test generators as shown on Section 14.1. 2) Let the EUT work in test mode and measure it. 3) The EUT are placed on an insulating support 0.1m high above a ground
reference plane. CDN (coupling and decoupling device) is placed on the ground plane about 0.3m from EUT. Cables between CDN and EUT are as short as possible, and their height above the ground reference plane shall be between 30 and 50 mm (where possible).
4) The disturbance signal described below is injected to EUT through CDN. 5) The EUT operates within its operational mode(s) under intended climatic
conditions after power on. 6) The frequency range is swept from 150kHz to 80MHz using 3V signal level,
and with the disturbance signal 80% amplitude modulated with a 1kHz sine wave.
7) The rate of sweep shall not exceed 1.5*10-3decades/s. Where the frequency is swept incrementally, the step size shall not exceed 1% of the start and thereafter 1% of the preceding frequency value.
8) Recording the EUT operating situation during compliance testing and decide the EUT immunity criterion.
14.5.2.For signal lines and control lines ports:
It’s unnecessary to test.
14.5.3.For DC output line ports:
It’s unnecessary to test.
