U8480 系列是是德科技首款支持低至直流测量范围的功率传感器（使用选件 200），特别适用于信号源/网络分析仪校准、功率参考以及 EMC 应用。
外部触发能够在接近信号本底噪声的小信号上进行精确触发。借助 U8480 系列功率传感器上的内置触发输入连接，您可以将信号源或被测器件提供的外部触发信号通过标配的 BNC 至 SMB 电缆直接传输到 USB 传感器。
U8480 系列功率传感器得到 Keysight BenchVue 软件的支持。BenchVue 软件使您无需编程，便可轻松控制功率计记录数据，并通过广泛的显示选件查看测量结果。只需将此传感器连接至安装有 BenchVue BV0007B 功率计/传感器控制和分析应用软件的计算机，便可执行平均功率测量与分析。
The Agilent/Keysight Technologies U8481A USB Thermocouple Power Sensor, DC/10 MHz to 18 GHz, -35 to +20 dBm, Refurbished is the company's first power sensor with the capability to measure down to DC. Now, with an expanded frequency range, it allows you to make fast and accurate high frequency power measurements in applications ranging from PNA/MXG calibration to high volume manufacturing.
The U8481A now computes real time measurement uncertainty in real time and at any given point, removing the need for manual MU calculations, shortening test time and providing highly accurate measurements. Users can also display power measurements and their measurement uncertainty simultaneously.
Additionally, you can achieve greater accuracy with the S-parameter and gamma correction features, which correct impedance mismatch errors as well as the errors caused by components inserted between the DUT and power sensor.
