2.3.Description of Test mode

Test mode: ON(Projection&Clock display&FM ON&USB output)

2.4.Classification of apparatus

Category I: apparatus containing no electronic control circuitry.

Category II: transformer toys, dual supply toys, mains powered motor operated appliances, tools, heating appliances and similar electric apparatus (for example – UV radiators, IR radiators and microwave ovens) containing electronic control circuitry with no clock frequency higher than 15MHz. Category III: equipment which in normal use, is not connected to a power network and has no cables attached. This category includes apparatus provided with rechargeable batteries, solar or other similar d.c. power sources which can be charged or operated by connecting the apparatus to the mains power.

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.Operating Condition of EUT

4.5.1. Setup the EUT as shown on Section 4.1.

4.5.2. Turn on the power of all equipments.

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.

5.5.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.


PASS. The frequency range from 30MHz to 300MHz is investigated. Note: Emissions attenuated more than 20 dB below the permissible value are not reported.

6.4.Test Procedure

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.


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.

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.

13.6.Test Result

PASS.

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.
