GENERAL 1.1 Introduction The following measurement report is submitted on behalf of SOLID YEAR CO., LTD. In support of a Class B Digital Device certification in accordance with Part2 Subpart J and Part 15 Subpart A and B of the Commission’s Rules and Regulations. 1.2 Description of EUT EUT: Keyboard Applicant: SOLID YEAR CO., LTD NO.3 PAO CHI LANE, CHUANG YA TSUN, SIU SHUI HSIANG, CHANGHWA HSIEN, TAIWAN R.O.C Manufacturer: SOLID YEAR CO., LTD NO.3 PAO CHI LANE, CHUANG YA TSUN, SIU SHUI HSIANG, CHANGHWA HSIEN, TAIWAN R.O.C Model No: ACK-280H FCC ID : L2BACEKEY280H Power Type: 5V DC form host computer. USB Cable: USB Connector x1(Shielded, 1.2 m long) The Keyboard is designed for PC system. EUT is the Windows 95 enhanced keyboard. During testing the EUT(Keyboard)was using the EMI-TEST software to set at Keyboard Test mode for each emission measured . This was done in order to ensure that maximum emission levels were attained.

So there is no need for additional I/O card. Two mouse were connected to USB port of EUT. A keyboard was connected to PS/2 port and A mouse was connected to other PS/2 port. A modem was connected to the series port and a printer was connected to the parallel port. Two telephone line(RJ11C cables) connected to the Phone Jack of modem and the Line Jack of modem. 1.5 Test Procedure All measurements contained in this report were performed according to the techniques described in Measurement procedure ANSI C63.4-1992 "Measurement of unintentional Radiators."

The final configuration of the test system and the mode of operation used during these tests were chosen as that which produced the highest emission levels. However, only those conditions, which the EUT was considered likely to encounter in normal use, were investigated. The system's radiated and conducted emissions were investigated. MAX LIGHT MEASUREMENT REPORT Page: 8/20 Report Number: MLT9902P15005FCC ID: L2BACEKEY280H Technology Lab II. Conducted Emissions Requirements 2.1 General & Setup : The power line conducted emission measurements were performed in a shielded enclosure. The EUT was assembled on a wooden table which is 80 centimeters high, was placed 40 centimeters from the backwall and at least 1 meter from the sidewall. Power was fed to the EUT from the public utility power grid through a line filter and EMCO Model 3825/2 Line Impedance Stabilization Networks (LISN). The LISN housing, measuring instrumentation case, ground plane, etc., were electrically bonded together at the same RF potential. The Spectrum analyzer was connected to the AC line through an isolation transformer. The 50-ohm output of the LISN was connected to the spectrum analyzer directly. Conducted emission levels were in the CISPER quasi-peak detection mode. The analyzer's 6 dB bandwidth was set to 9 KHz. No post-detector video filter was used. The spectrum was scanned from 450 KHz to 30 MHz. The physical arrangement of the test system and associated cabling was varied (within the scope of arrange…
