但无源探头还需要提供极小的电容负载和宽带宽，以与示波器的输入带宽保持一致。例如，泰克 TPP1000 无源探头提供 1 GHz 带宽，小于 4 pF 的电容负载，有助于保持信号完整性。KHCednc 图 1：探头的额外电容会增加电阻值和电容值，从而增加测量的上升时间。

持续测量 AC-DC 和 DC-DC 转换器的性能可能是一项极具挑战性的任务。随着设计师努力从硅基电源转换器过渡到碳化硅 (SiC) 和氮化镓 (GaN) 等宽禁带 ...

关注公众号：工程师看海 示波器因为有探头的存在而扩展了示波器的应用范围，使得示波器可以在线测试和分析被测电子电路，如下图： 探头的选择和使用需要考虑如下两个方面： 其一：因为探头有负载效应，探头会直接影响被测信号和被测电路 ...
