  • 一流的功率线性度：小于 0.8%
  • 宽动态范围：-35 dBm 至 +20 dBm
  • 精确校准并可追溯至美国国家标准与技术研究所（NIST）或国家物理实验室（NPL）
  • 仪器现在内置 BenchVue 软件许可证（BV0007B）。 BenchVue 简化了仪器的连接和控制，并自动化测试序列

执行低至直流范围的测量

U8480 系列是是德科技出品的第一款能够执行低至直流范围的测量（与选件 200 结合）的功率传感器。 这对信号源/网络分析仪校准和功率参考以及 EMC 应用特别有用。

内置外部触发器输入

外部触发器可使接近信号本底的小信号得到精确触发。 通过 U8480 系列功率传感器上的内置触发器输入连接，您可以通过标准 BNC-SMB 电缆将来自信号源或被测器件的外部触发信号直接连接至到 USB 传感器。

从 PC 直接测量

U8480 系列由是德科技 BenchVue 软件支持。 BenchVue 让您可以很容易地控制功率计来记录数据，并以广泛的显示选项阵列可视化测量结果，而无需任何编程操作。 只需将传感器连接至您的 PC 上安装的 BenchVue BV0007B 功率计/传感器控制与分析应用程序，即可执行平均功率的测量与分析。
