GENERAL 1.1 Introduction The following measurement report is submitted on behalf of PC EXPERT TECH 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: IR Wireless Keyboadr (RX) Applicant: PC EXPERT TECH CO.,LTD. 2031 O’Toole Avenue San Jose, CA 95131-1301 Manufacturer: PC EXPERT TECH CO.,LTD. 2031 O’Toole Avenue San Jose, CA 95131-1301 Model No: OA-7500-5 / OA-7500-6 / OA-7500-7 / OA-7500-8 FCC ID : KFJIKB975 Power Type: 5V DC form host computer. PS/2 Cable: PS/2 connectorx2(Shielded, 65 cm long) The Wireless Keyboard is designed for PC system which built-in Infra-Red technology. EUT is the wireless keyboard’s infra-red receiver. During testing the wireless keyboard (TX) was pressed “H” key continuously. This was done in order to ensure that maximum emission levels were attained.

Computer: COMPAQ Model No.: 3284 Serial No.: L708BKTB4154 FCC ID: EJH3284 Monitor: COMPAQ Model No.: 303U Serial No.: 704AG19TG099 FCC ID: BJMCM14UH Printer: PANASONIC Model No.: KX-P1080I Serial No.: 7CKAKE98933 FCC ID: ACJ5Z6KX-P10801 Modem: Askey (External Fax / Data Modem) Model No.: WS1414VE Serial No.: IAH-10811 FCC ID: H8N1414VE MAX LIGHT MEASUREMENT REPORT Page: 6/20 Report Number: MLT9907P15004FCC ID: KFJIKB975 Technology Lab 1.4 Configuration of System Under Test During testing the EUT(Wireless Keyboard’s infra-red receiver) was connected to the two Compaq PC’s PS/2. So there is no need for additional I/O card. 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." Power Supply PC Monitor Printer Keyboard EUT RJ11C Cables RS-232RS-232 Modem MAX LIGHT MEASUREMENT REPORT Page: 7/20 Report Number: MLT9907P15004FCC ID: KFJIKB975 Technology Lab 1.6 General Test Condition The conditions under which the EUT operates were varied to determine their effect on the equipment's emission characteristics. 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: MLT9907P15004FCC ID: KFJIKB975 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…
