NEUTRON EMC LAB. FCC ID: E8HKBR9930 1. GENERAL INFORMATION 1-1. Product Description The Chicony Electronics Co., Ltd. Model KBR9930(referred to as the EUT in this report) is a RF keyboard transmitter that uses FSK(Frequency Shift Keyed) mode frequency modulation radio technology to operate a receiver Model:KBR9930, which designed as an " Input Device " for compatible with a PS/2 interface protocol PC system. The EUT is a part of this composite system which considered as a short range, low power communication device transmitter. Details of technical specification for EUT, refer to the follows: (1) Transmitter Frequency Designation Operating Frequency Range : 26.955 MHz to 27.070 MHz Frequency Band : 26.960 , 26.975 , 26.990, 27.005, 27.020, 27.035, 29.050, 27.065 (in MHz) 8 channels, selectable. Channel setting by software control. Frequency Tolerance : 5 KHz @ center frequency for each channel. Channel Separation : 15 KHz (2) Effective Radiated Power and Distance Radiated Power : 1 mW max. (3) Power Rating Keyboard: 3V , 30 mA(Max.) (4) Operation Methodology The keyboard encoder generates a pulse code serially transmit (typical designation) into the modulator(or called as mixer) stage in circuit. This pulse signal mixed with the carrier at modulator(mixer) stage by way of FSK mode frequency modulation. The modulation depth is designed such as ± 5KHz in this application, that means the pulse(may be at high level state or low level state) will trigger the oscillator to generate a frequency at a specified fundamental frequency +5KHz or −5KHz, depended on the designation. For example, if the carrier frequency defined as fundamental frequency +5KHz at high level state, then the alternative carrier frequency will be fundamental frequency −5KHz at low level state. Then the modulator(mixer) will output a modulated signal into RF amplifier stage and finally to the transmit antenna. 1-2. Related Submittal(s) / Grant (s) This submittal(s) is intended for FCC ID: E8HKBR9930 filing to comply with Section 15.227 of the FCC Part 15, Subpart C Rules. The receiver in compliance with FCC Part 15, Subpart B is authorized under a DoC procedure. 1-3. Test Methodology Both conducted and radiated testing were performed according to the procedures in ANSI C63.4 (1992). Radiated testing was performed at an antenna to EUT distance 3 meters. 1-4. Test Facility The open area test site and conducted measurement facility used to collect the radiated data is located on the address of No. 132-1, Lane 329, Sec. 2, Palain Road, Shijr Jen, Taipei, Taiwan, R.O.C. of NEUTRON ENGINEERING INC. This site has been fully described in report dated Jun. 4, 1999 Submitted to FCC office, and accepted in a letter dated Sep. 02, 1999 (Reg. No. 95335).
