88 KBT system description Define by Panny Tam 01/06/26 11:31 AM Free board 2FT transmitter 1. MCU will scan the key matrix, ID key, channel key and the movement of track ball. If any signal change come from above mention. It will turn convert the data package with checking the low battery status data, and prepare for modulate to the VCO directly. 2. When MCU received the signal of any key, or from track ball. Firstly, MCU will turn on the RF power, program the synethizer code of PLL( phase lock loop), PLL will lock the exact frequency.( eg. 26.985MHz) 3. The reference LO( local oscillator) will support the exact 10.24MHz to the PLL and VCO, to compare the phase to let VCO to lock the exact frequency(e.g. 26.985MHz) 4. Buffer amplifier is to change the impedance between VCO (high impredance) to low impredance 5. (PA)Power amplifier is to support enough current to drive the antenna 6. Matching circuit is to match the impredance between PA and antenna. Free board 2FT receiver 1. When the PC power on, the receiver will start the PnP process. No-matter the interface is PS2 or USB 2. MCU will program the synethizer code of PLL( phase lock loop), PLL will lock the exact frequency.( eg. 37.680MHz) of VCO 3. When the RF signal comes(e.g. 26.985MHz), the low noise amplifier (LNA) will amplify the signal about 14 dB. 4. The adding signal to pass through mixer 1 will generate 10.695MHz intermediate frequency(IF). It means that the original signal (26.985MHz) will down convert to 10.695MHz 5. IF1 filter is perform a filtering function of 10.695MHz (IF1) 6. Reference crystal not only perform the reference function, and also with the local oscillator (LO)function 7. When the IF signal pass through the second mixer, it will generate the second IF2 455KHz. 8. After the IF2 amplifier will work for a AGC (auto gain control) function, and the signal more stable 9. A 455KHz resonator will perform the LO function. 10. When the IF2(455KHz) pass through discriminator, the demodulating signal will come out. We called it base band signal. 11. AF AMP will work as a data slicer, it amplify the signal to square wave digital signal. 88 KBT system description Define by Panny Tam 01/06/26 11:31 AM 12. This digital signal will send to MCU. MCU will sample the signal to check it is valid or not. 13. If the signal it valid, MCU will convert the signal of the interface to PC. No- matter is PS2 or USB and let PC to do their exact activity. 14. MCU also scan the reset lock key to check user has to press this key or not.

However, occasionally outside sources may cause interference. Test method: All measurements contained in this report were performed according to the techniques described in Measurement procedure ANSI C63.4 – 1992. Pretest was found that the emission of operating mode is worse than standby mode. So, The final test is made at the operating mode. While testing, the EUT was made to transmit continuously and adjusted at a position, which transmitted the maximum emission. The test placement as the photographs showed is the worst case 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.

The EUT is assembled on a wooden table, which is 80 cm high, is 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 max. peak mode . But if the max. peak mode failed or over average limit, it will be measured by average detection mode. While testing, there is the worst-emission plot printed at peak detection mode, and there are more than 6 highest emissions relative to limit recorded. The plot is kept as the original data, not included in test report.
