纵览全局，洞悉入微

  • 非常适合捕获和分析被测器件中的低电平电流以表征子电路，或者测量无线电池供电设备或集成电路的电流消耗
  • 使用电流波形的可选高增益或低增益视图进行正常动态范围的测量
  • 探头附件可包含在探头中，也可单独订购：可更换的传感器头、MBB 插座、接头和连接线
     

随着现代电池供电设备和集成电路更加环保和节能，越来越需要进行高灵敏度、低电平电流测量，以确保这些设备的电流消耗在允许的限制范围内。N2821A 高灵敏度探头旨在进行高动态范围、高灵敏度测量，以满足当今的挑战性电流测量需求。

超灵敏的 N2821A 交流/直流电流探头可支持在是德科技示波器上进行 50 uA 到 5 A 范围内的测量。N2821A 接口采用先通后断（MBB）连接器，让您可以快速探测被测器件上的多个位置，而无需焊接或焊开引线。

N2820A 双信道电流探头连接至两个示波器信道，以同时提供更宽动态范围测量的低增益和高增益视图，而 N2821A 单信道电流探头一次只提供一个用户可选视图。

与 Infiniium S 系列高清示波器结合使用，打造终极高灵敏度测量解决方案。使用 Infiniium 示波器上的曲线下面积测量（电荷），您可以轻松计算出一段时间内的集成电流消耗（以库仑为单位）。
