How do I use an oscilloscope?

common problems 3460

市面上有许多品牌和类型的示波器,它们可能看起来各不相同,但大多数都有相同的基本步骤。以下是如何使用示波器的分步指南:

  1. 连接探头: 将探头连接到示波器的输入通道。确保连接牢固。如果您有衰减探头,可能需要补偿探头,直到获得完美的方波。
  2. 测试DUT: 通过将探头尖端连接到电路中的感兴趣点并将接地夹连接到DUT上的公共接地点,将探头连接到被测设备(DUT)。
  3. 调整垂直和水平刻度: 使用示波器控件调整垂直(电压)和水平(时间)刻度。这确保波形在屏幕上正确显示。
  4. 设置触发器: 使用触发设置来稳定波形。触发器有助于确保信号稳定显示。根据需要调整触发电平和类型。
  5. 解释波形: 查看屏幕上的波形。x轴代表时间,y轴代表电压。观察信号的形状、频率和幅度。
  6. 分析波形: 识别任何问题或异常。信号表现是否如预期?是否有噪声尖峰或不规则?排除检测到的任何问题,以确保信号性能准确。您可以使用示波器的功能,如游标和自动测量,来辅助分析。

  • How to read the measurement results of a digital multimeter?

    362

    Most handheld or benchtop digital multimeters display measurements digitally. The number of digits displayed on the screen usually represents the measurement resolution of the digital multimeter. Resolution is the smallest detail that a digital multimeter can quantitatively determine when making a measurement. Therefore, the more digits a digital multimeter displays, the higher its resolution. Handheld digital multimeters are typically capable of displaying three-and-a-half and four...

  • What is alternating current (AC)?

    280

    Alternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...
