4 Test Report /29 Chapter 1 Introduction Description of EUT This EUT is a Optical 5-button mouse. Connections of EUT (1) The USB port is connected with the USB interface of PC. Test method: The applicant provides the testing program. Pretest was found that the emission of operating mode is worse than standby mode. So, The final test is made at the operating mode. The radiation pretest found out this mode was the worst case. We only recorded the worse case in this report. The test voltage is120vac / 60Hz. The test placement as the photographs showed is the worst emission placed. (If the emission is close to the ambient, the resolution BW and view resolution will be reduced and the data will be recorded by detection of maximum hold peak mode.) The testing configuration of test setup is showing in the next page.

9 Test Report /29 Chapter 2 Conducted Emission Test Test condition and setup All the equipment is placed and setup according to CISPR 22. Mains power: The EUT is assembled on a wooden table, which is 80 cm high and placed 40 cm from the back-wall, which is a vertical conducting plane. One LISN is for EUT, the other LISN is for support equipment. They are all placed on the conductive ground. The EUT s LISN connect a line switch box for selecting L1 or L2, then connect to a preamplifier and spectrum. The spectrum scans from 150KHz to 30MHz. Conducted emission levels are detected at maximum peak mode. But if the maximum peak mode failed or over average limit, it will be measured by average detection mode. While testing the worst-emission plot printed in the peak detection mode, and there are up to 6 highest emissions to be recorded. The plot is kept as the original data and not included in the test report.

12 Test Report /29 Chapter 3 Radiated Emission Test Test condition and setup Pretest: Prior to the final test (OATS test), the EUT is placed in a shielded enclosure, and scan from 30MHz to 1GHz. This is done to ensure the radiation is exactly emitted from the EUT. Final test: Final radiation measurements are made on a 10 meter, open-field test site. The EUT is placed on a nonconductive table, which is 0.8m height, the top surface is 1.0 x 1.5 meter. The entire placement is according to CISPR 22. The spectrum is examined from 30 MHz to 1000MHz measured by HP spectrum. The range Antenna is used to measure frequency from 30 MHz to 1GHz. The final test is used the spectrum analyzer. Measure more than six top marked frequencies generated form pretest by computer step by step at each frequency. The EUT is rotated 360 degrees, and antenna is raised and lowered from 1 to 4 meters to find the maximum emission levels. The antenna is used with both horizontal and vertical polarization. Appropriated preamplifier which is made by TRC is used for improving sensitivity and precautions are taken to avoid overloading. The spectrum analyzer s 6dB bandwidth is set to 120 khz, and the EUT is measured at quasi-peak (below 1GHz) mode. If the emission is close to the frequency band of ambient, the tester will recheck the data and the corrected data will be written in the test data sheet. If the emission is just within the ambient, the data from shielded room will be taken as the final data.
