4. 조립 설명서
Follow these steps carefully to assemble your Weytoll XR2206 Signal Generator. A soldering iron, solder, and basic hand tools are required.
- PCB를 준비하세요: Inspect the Printed Circuit Board for any defects.
- Install Resistors and Capacitors: Solder the resistors and non-polarized capacitors onto the PCB according to their marked values and positions. Pay attention to the polarity of electrolytic capacitors.
- IC 소켓을 설치하세요: Solder the 16-pin IC socket onto the PCB. Ensure the notch on the socket aligns with the notch on the PCB silkscreen.
- Install Potentiometers: Solder the three potentiometers (Coarse, Fine, Amplitude) into their designated positions.
- Install Power Jack and Terminal Block: Solder the DC power jack and the 3-pin terminal block onto the PCB.
- Install XR2206 IC: Carefully insert the XR2206 IC into its socket, ensuring the notch on the IC aligns with the notch on the socket and PCB.
- Assemble Acrylic Case: Peel off the protective film from the acrylic case parts. Assemble the case around the completed PCB using the provided screws and nuts.
- 최종 확인: Before applying power, visually inspect all solder joints for shorts or cold joints. Ensure all components are correctly oriented.

5. 사용 설명서
This section details how to power on and operate your signal generator.
5.1 전원 켜기
- Connect a 9-12V DC power supply to the DC power jack. Alternatively, a 9V battery can be used (not included).
- Ensure connections are secure before applying power.
5.2 파형 선택
The kit supports sine, triangle, and square waveforms. Select the desired waveform using the jumpers on the PCB (J1, J2, etc., as marked for Sine/Triangle/Square).
5.3 주파수 조정
The frequency range is 1Hz to 1MHz. Use the "Coarse" potentiometer for broad frequency adjustments and the "Fine" potentiometer for precise tuning.
5.4 Amp광도 조정
Adjust the output signal amplitude using the "Amplitude" potentiometer.
5.5 출력 연결
Connect your testing equipment (e.g., oscilloscope, frequency counter) to the output terminals on the 3-pin terminal block (marked S/N/TR/SQU and GND).
