JYETech DSO 138 DIY KIT 13803K Digital Oscilloscope Instruction Manual

1.製品オーバーview

The DSO138 is engineered as a training oscilloscope kit, emphasizing fundamental oscilloscope functions for straightforward assembly and operation. It incorporates a Cortex-M3 ARM processor (STM32F103C8) and a 2.4-inch TFT LCD, providing clear waveform visualization. This specific 13803K kit features pre-soldered Surface Mount Device (SMD) components and a pre-programmed Microcontroller Unit (MCU), which simplifies the initial assembly process.

2. セットアップと組み立て

While the SMD components are pre-soldered and the MCU is pre-programmed, the assembly of through-hole components and general soldering are still required for other parts of the kit. Please refer to the detailed assembly instructions and schematics provided with your physical kit for precise, step-by-step guidance.

電源要件： A 9V DC power supply is essential for the operation of the DSO138 and is not included with this kit. Ensure that the power supply you use is compatible with the device's specifications.

3. 操作手順

The DSO138 provides essential oscilloscope functionalities for signal analysis.

主な特徴:

• アナログ帯域幅: 0～200KHz
• Sampリンレート： 1Msps max
• 感度： 10mV/div - 5V/div
• 垂直解像度: 12ビット
• タイムベース: 10us/Div - 500s/Div
• レコード長: 1024ポイント
• テスト信号： Built-in 1KHz/3.3V test signal for calibration and testing
• ホールド機能: Waveform frozen (HOLD) function available for detailed analysis

Connecting and Displaying Waveforms:

Connect your signal source to the input BNC connector. Utilize the onboard controls to adjust the vertical sensitivity (V/Div) and timebase (s/Div) settings. These adjustments are crucial for properly scaling and displaying the waveform on the 2.4-inch TFT LCD in real-time.

4. メンテナンス

To ensure the longevity and optimal performance of your DSO138 oscilloscope, follow these maintenance guidelines:

• 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。研磨剤入りの洗剤や溶剤の使用は避けてください。
• 環境条件: Do not expose the oscilloscope to extreme temperatures, high humidity, or direct sunlight. Store it in a dry, stable environment.
• 取り扱い： 物理的な損傷を防ぐため、デバイスを丁寧に取り扱ってください。落としたり、強い衝撃を与えたりしないでください。
• 変更点: Do not attempt to modify the internal circuitry beyond the intended assembly steps. Unauthorized modifications can void any potential warranty and may damage the device.

5。 トラブルシューティング

This section addresses common issues you might encounter with your DSO138 kit.

よくある問題:

• ディスプレイまたは電源がありません: Ensure the 9V DC power supply is correctly connected and functioning. If the kit was recently assembled, double-check all power-related connections and soldering points for continuity and shorts.
• Distorted or Unstable Waveforms: Verify that the probe is securely connected and that its 1X/10X switch (if present) is set appropriately for your measurement. Adjust the vertical sensitivity (V/Div) and timebase (s/Div) settings on the oscilloscope to properly scale the waveform.
• コンポーネントの過熱: If any component, such as a diode (e.g., D2), becomes excessively hot during operation, immediately disconnect power. This often indicates a short circuit, an incorrectly installed component, or a faulty part. Consult the provided schematic for correct component placement and values.

For more detailed troubleshooting steps, refer to the comprehensive troubleshooting guide and schematic included with your kit. If issues persist, contact JYETech customer support for further assistance.
