亮点

带宽：

  • 30 GHz（典型值）
  • Tr = 14.5 psec（10-90%，仅使用 N2803A 的探头）

输入阻抗

  • 直流输入电阻：55 Ω 至 Vterm
  • 输入电阻 > 10 kHz：50 Ω 至 0.909 x Vterm

输入电压范围

  • 输入电压范围：2.5 Vrms

N5444A Infiniimax III 2.92 mm/3.5 mm/SMA 探头提供 28 GHz 带宽，允许您连接两根 2.92 mm、3.5 mm 或 SMA 电缆以在单个示波器通道上进行差分测量。

订购 N5448B 2.92 mm 探头柔性电缆（10” 或 25 cm 长）可以延长电缆长度，增加便利性。 与所有 InfiniiMax III 探头放大器兼容。

N5444A 提供对公共直流电压的端接，而不是对地端接，这是许多信号标准的要求。 其实现方式：从直流至 ~1kHz，端接为 55 Ω 至端接电压；~10 kHz 以上，端接为 50 Ω 至 0.9 倍端接电压。 端接电压范围为 ±4 V（最小步长：5 mV），最大电流为 80 mA。 终端电压可以由示波器内部控制，也可以使用提供的直流插孔从外部施加。
