5 Electromagnetic Interference (EMI)
5.1 Radiated Disturbance 30MHz to 6000MHz 5.1.1 Test Procedure
The test site semi-anechoic chamber has met the requirement of NSA tolerance 4dB according to the standards: ANSI C63.4. The test distance was 3m for 30 ~ 1GHz. The test site full-anechoic chamber has met the requirement of VSWR tolerance 6dB according to the standards: CISPR 16-1-4. The test distance was 3m for 1GHz ~ 6GHz. The set-up and test methods were according to EN 55022/CISPR 22 A preliminary scan and a final scan of the emissions were made from 30 MHz to 1GHz by using test script of software; the emissions were measured using Quasi-Peak Detector (30MHz~1GHz) and AV/PK Detector (above 1GHz).. The maximal emission value was acquired by adjusting the antenna height, polarisation and turntable azimuth in accordance with the software setup. Normally, the height range of antenna was 1m to 4m, the azimuth range of turntable was 0°to 360°, The receive antenna has two polarizations V and H.

5.2 Conducted Disturbance 0.15 MHz to 30MHz On AC Port 5.2.1 Test Procedure
The EUT was configured as described in section 4 for this test. The mains cable of the EUT being measured shall be connected to LISN, The LISN shall be placed 0.8m from the boundary of EUT and bonded to a ground reference plane for LISN mounted on top of the ground reference plane. This distance is between the closest points of the LISN and the EUT. All other units of the EUT and associated equipment shall be at least 0.8m from the LISN. All telecommunication and signal ports must be correctly terminated using either appropriate associated equipment or a representative termination during the measurement of the conducted disturbances at the mains. Ground connections, where required for safety purposes, shall be connected to the reference ground point of the LISN and, where not otherwise provided or specified by the manufacturer, shall be of same length as the mains cable and run parallel to the mains connection at a separation distance of not more than 0.1m. The set up of Conducted Disturbance for telecommunication port was according to Annex C of EN 55022/CISPR 22.

6.6.3 Test Results
In the case where the equipment is fitted with or connected to a battery back-up, the performance criteria for transient phenomena shall apply. In the case where the equipment is powered solely from the AC mains supply (without the use of a parallel battery back-up) volatile user data may have been lost and if applicable the communication link need not to be maintained and lost functions should be recoverable by user or operator; no unintentional responses shall occur at the end of the test.

8 System Measurement Uncertainty
For a 95% confidence level, the measurement expanded uncertainties for defined systems, in accordance with the recommendations of ISO 17025 were:
System Measurement Uncertainty
Items Extended Uncertainty
Radiated Emission in 3m chamber 30MHz-1000MHz
Horizontal: 4.83dB; Vertical: 4.91dB;
CE 3.50dB
Uncertainty for Harmonic test 3.26%
Uncertainty for Flicker test 4.76%
Uncertainty for RS test 19%, K=2
Uncertainty for CS test 29%, K=2
Uncertainty for ESD test The immunity measurement system uncertainty is within standard requirement and is based on a
standard uncertainty multiplied by a coverage factor k=2, providing a level of confidence of
approximately 95%.
Uncertainty for EFT test
Uncertainty for Surges test
Uncertainty for Voltage Dips, Voltage Variations and Short Interruptions Test
