IEM-516T 1. MIC INPUT OR L/R RCA INPUT=>IC1DUAL Preamplifier wit ALC LR The signal from MIC input or L/R RCA input will be dual pre-amplified by IC1 ( with ALC – Auto Level Control function ) and output a corresponding single signal or L/R signal . 2. The treble ( of the output ) will be improved first via the pre-emphasis net-work 3. IC3HEADPHONE AMPLIFIER MONITOREARPHONE The output signal can be also monitored via the earphone after it is amplified by IC3 ( headphone amplifier ). 4. IC8,IC9IC4~IC7LED DRIVE IC, LEDT Any change of the signal will be displayed on LED by the driving of IC4 ~ IC7 ( LED drive IC ) after it is amplified by another stage via IC8 & IC9. 5. LRIC2 The L/R signal after pre-emphasis can be stereo modulated via IC2 ( stereo modulator ) . 6. VCORF The modulated signal can be transmitted via the carrier produced by the VCO . To cover the scope which the receiver can effectively receive the amplifier chain is used to improve the RF gain to ensure the efficient transmission. 7. VCOIC13 The frequency produced by the VCO does also reach IC13 to perform the function of frequency phase detection. 8. SW2CHANNEL CONTROL SWITCH, SWITCH CHANGE DATA, IC13VCOCHARGE PUMPIC13IC10, IC11 CHANNEL The channel will be switched by SW2 ( channel control switch ) , and the data derived from the switch changing will be writed into IC13 to decode to perform the function of phase detection , accompany with the frequency produced by the VCO , a charge pump is output to control the transmission frequency . The same time , control signal from IC13 will also reach IC10 & IC11 to drive the seven section LED to display the channel being used .

Measurement Procedure 1. Connect the EUT as Section 4.2 . 2. Plot the unmodulated chart shows on spectrum. 3. Set the output of the signal generator to 1kHz, 2.5kHz, 9.448kHz and 15kHz. Increase the amplitude of the signal, while monitoring the modulation meter. Until modulation is max. Measure the bandwidth under 26 dB compared to the unmodulated fundamental carrier peak level of the modulated signal displayed on the spectrum analyzer. 4. The occupied Bandwidth was measured as follow pages.
