Circuit Description of Receiver(RX) (Ultra-e-2010, 2020, 2030) 1. RF Receiving Circuit A. Unnecessary signal and noise in the signal received from transmitter is filtered in the Resonance Circuit(L1,C1) and Transistor(Q1) makes the filtered signal clearer. The cleared signal enters into Oscillation & Detection Circuit through Condenser(C4). B. Oscillation & Detection Circuit The signal from Transistor(Q1) is mixed up and detected in Oscillation & Detection Circuit(Q2). The high frequency signal and noise in detected signal are filtered in Coil(L3) and enters in Amplification Circuit. C. Amplification Circuit The detected signal is amplified and converted into square-wave pulse in Amplification Circuit and goes into MPU(U4) 2. MPU(Micom) MPU analyzes the pulse coded signal received from transmitter. When this pluse coded signal is the same as the pluse coded signal stored in Memory Chip(U2), the following functions are performed. A. Stimulation Function When the pulse coded signal from the transmitter is the same as the stimulation signal stored in Memory Chip(U4), this signal is transferred into Analog Switching Circuit(U2 on Main PCB) Out-put from one of 8 pots in Analog Switch goes into Transistor(Q8) which has the adjusted intensity level. When the Transistor(Q8) supplies with the received signal to the Transistor(Q7), Transformer(T1) boosters the voltage several hundreds times. B. Vibration Function When the pulse coded signal from the transmitter is the same as vibration signal stored in Memory Chjp(U4), this signal is transferred into Transistor(Q6) and Vibration motor is operated. C. Beep Function When the pulse coded signal from the transmitter is the same as beep signal stored in Memory Chip(U4), this signal is sent to Transistor(Q5) and Beeper is operated. D. Intensity Level Adjustment Function When the pluse coded signal from the transmitter is the setting signal of intensity level, this signal is stored as the adjusted intensity level in EEP Rom(U2 on control PCB). 3. Power Circuit A. When magnet on the buckle of receiver belt touches Reed Switch in receiver unit, power is supplied to main circuit by Transistor(Q3). And then MPU(Micom) starts operation, power is supplied continuously after removing the magnet from Reed Switch. B. Voltage Regulation Circuit Voltage Regulation IC(U5) converts 6volt into constant-voltage regulated power(4volt).

Test Procedure 1.1 Preliminary Testing for Reference Preliminary testing was performed in a KTL absorber-lined room to determine the emission characteristics of the EUT. The EUT was placed on the wooden table which has dimensions of 0.8 meters in height, 1 meter in length and 1.5 meters in width. Receiving antenna (Biconical antenna : 30 to 300 MHz, Log-periodic antenna : 200 to 1000 MHz or Horn Antenna : 1 to 18 GHz) was placed at the distance of 1 meter from the EUT. In order to cohere the individual components of the characteristic broadband emission from the receiver(EUT), a RF generator(CW signal) and a log-periodic antenna were used. The frequency and output level of the generator were adjusted for highest observed coherent receiver emissions on the spectrum analyzer with RF amplifier. An attempt was made to maximize the emission level with the various configurations of the EUT. The effect of changing the position of the cable was observed to find the worst case configuration while rotating the table and varying antenna height and it’s polarization. Radiated and spurious emissions were checked from 30 MHz to 3000 MHz according to section 15.33. 1.2 Final Radiated Emission Test at an Absorber-Lined Room The final measurement of radiated field strength was carried out in a KTL Absorber-Lined Room that was listed up at FCC acc…
