4. 組み立て手順
Assembly of this kit requires basic soldering skills and tools (soldering iron, solder, wire cutters, multimeter recommended). Follow the steps below carefully.
- コンポーネントの識別: Before soldering, identify all components using the provided circuit diagram (if included, otherwise refer to component markings). Sort resistors by value, capacitors by type and value, and identify integrated circuits (ICs).
- 最初に小さい部品をはんだ付けする: Begin by soldering the smallest components to the PCB, such as resistors and diodes, followed by capacitors, IC sockets (if using), and then the ICs themselves. Pay attention to polarity for diodes, electrolytic capacitors, and ICs.
- Install Larger Components: Solder the larger components like potentiometers, connectors (power jack, output terminals), and switches. Ensure they are flush with the PCB and correctly oriented.
- Verify Soldering: After all components are soldered, carefully inspect all solder joints for bridges, cold joints, or missing connections. Use a multimeter to check for continuity where appropriate.
- Assemble Acrylic Casing:
- Remove protective film from both sides of the acrylic panels.
- Attach the bottom acrylic panel to the PCB using the provided standoffs and screws.
- Align the top acrylic panel, ensuring all potentiometers, switches, and connectors fit through their respective openings. Secure with the remaining screws.

5. セットアップ
Once assembled, follow these steps to set up your signal generator:
- 電源接続: Connect a DC power supply (9V to 15V) to the power input jack. Ensure correct polarity.
- 出力接続: Connect the signal output (OUT) to your desired measurement device (e.g., oscilloscope, frequency counter) using appropriate cables. The SYNC OUT provides a synchronization signal.
- 初期設定： Before powering on, set all potentiometer knobs to their center positions or minimum values to avoid unexpected outputs.
6. 操作手順
The Weytoll Signal Generator Kit allows for adjustment of frequency, duty cycle, DC offset, and amplitude. It can generate sine, square, triangular, and sawtooth waveforms.
Figure 6.1: Control knobs for signal adjustment.
- Frequency Adjustment (FREQ): Use the FREQ knob to adjust the output frequency from 1Hz to 20MHz.
- Duty Cycle Adjustment (DUTY): Use the DUTY knob to adjust the duty cycle of square and sawtooth waves from 15% to 85%.
- DC Offset Adjustment (OFFSET): The OFFSET knob allows for adjusting the DC offset of the output signal from -5V to +5V.
- Amplitude Adjustment (AMP): 使用 AMP knob to adjust the peak-to-peak amplitude of the output signal from 0.1VPP to 9.5VPP (with a 9V operating voltage）。
- 波形の選択: The kit supports output of triangular, square, sine, and forward/reverse sawtooth waves. Refer to the PCB markings or a detailed circuit diagram for specific waveform selection points or switches, if present.
- Synchronization Output (SYNC OUT): This terminal provides a synchronization signal, useful for triggering oscilloscopes or other external devices.
7. メンテナンス
The Weytoll Signal Generator Kit requires minimal maintenance:
- クリーニング： デバイスを清潔に保ち、ほこりを取り除いてください。清掃には柔らかく乾いた布を使用してください。液体洗剤は使用しないでください。
- ストレージ： Store the device in a dry, cool environment when not in use.
- 検査： Periodically inspect the connections and solder joints for any signs of wear or damage.
