Follow these steps to set up your DSO-2104 oscilloscope for initial use:

1. 짐 풀기: Carefully remove the oscilloscope and all accessories from the packaging. Verify that all components are present and undamaged.
2. 전원 연결: Connect the provided power cable to the power input on the rear panel of the oscilloscope and then to a suitable AC power outlet (100-240V, 50/60Hz). Ensure the power outlet is properly grounded.
3. 프로브 연결: Connect the oscilloscope probes to the desired BNC input channels (CH1, CH2, CH3, CH4) on the front panel. Ensure a secure connection.
4. 프로브 보상: Before taking measurements, it is recommended to compensate your probes. Connect the probe to the probe compensation output (usually a square wave signal) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.
5. 전원 켜기: Press the power button, typically located on the front panel, to turn on the oscilloscope. The display will illuminate, and the system will boot up.

5. 사용 설명서

The DSO-2104 offers a range of functions for waveform analysis. Here are basic operating guidelines:

5.1 기본 측정

• 대역폭: The device operates at a 100 MHz bandwidth across 4 channels.
• Samp링 비율: 최대 sampling rate is 1 GSa/s, allowing for detailed capture of fast signals.
• 수직 해상도: With an 8-bit vertical resolution, the oscilloscope provides good precision for voltag측정.
• 표시하다: Waveforms are displayed on the 7-inch (17.78 cm) LCD screen (800 x 480 pixels).

5.2 Adjusting Waveforms

• 세로축 눈금(볼트/분할): Use the vertical control knobs for each channel (CH1-CH4) to adjust the voltage scale, changing the vertical amplitude of the displayed waveform.
• 수직 위치: Use the position knobs to move the waveform vertically on the screen.
• 수평 스케일(시간/분할): Use the horizontal control knob to adjust the time base, changing the horizontal compression or expansion of the waveform.
• 수평 위치: Use the horizontal position knob to shift the waveform left or right.

7.2 파형이 표시되지 않음

• 프로브 연결 확인: 프로브가 입력 채널과 테스트 대상 회로에 올바르게 연결되었는지 확인하십시오.
• Check Channel Enable: Verify that the desired input channel is enabled on the oscilloscope.
• 수직 크기 조정: The waveform might be off-screen. Adjust the Volts/Div knob to a suitable range.
• 수평 크기 조정: The waveform might be too compressed or expanded. Adjust the Time/Div knob.
• Check Trigger Settings: Incorrect trigger settings can prevent a stable waveform display. Try "Auto" trigger mode or adjust the trigger level.
• 실행/중지 버튼: Ensure the oscilloscope is in "Run" mode (not paused).

7.3 불안정한 파형

• Adjust Trigger Level: Fine-tune the trigger level to a stable point on the waveform.
• Select Correct Trigger Type: Choose the appropriate trigger type (e.g., Edge, Pulse) for your signal.
• Check Probe Compensation: Improperly compensated probes can lead to distorted waveforms. Perform probe compensation if necessary.
