N2819A 差分探头可提供准确的高速差分信号测量结果，满足当今高速功率测量、车载总线测量和高速数字系统设计的需求。 N2819A 差分探头提供了 10:1 衰减设置，因此适用范围十分广泛。 这款探头配有丰富的探针附件，可以探测狭小空间内的大小元器件。 它还配有一个隔直流电容器，能够阻挡输入信号中不需要的直流分量。
这个差分探头的输入电阻为 200 kΩ，输入电容仅为 1 pF，可以尽量减少带给电路的负载效应。 N2819A 探头与配有 50 Ω AutoProbe 输入接口的部分 InfiniiVision 和 Infiniium 示波器兼容。 探头可由 InfiniiVision 和 Infiniium AutoProbe 接口直接供电。 若需配合无 AutoProbe 输入接口的示波器一起使用，请选择 N2793A。
