可進行低至直流範圍的量測

U8480 系列是是德科技第一套具有直流量測功能的功率感測器（搭配選項 200）。 如需執行信號源/網路分析儀校驗和功率參考，以及 EMC 應用，這是非常實用的功能。

內建外部觸發輸入

其外部觸發功能可準確觸發非常接近信號雜訊底線的小信號。 透過 U8480 系列功率感測器內建的觸發輸入連接，您可使用標配的 BNC 轉 SMB 纜線，將來自信號源或待測裝置的外部觸發信號，直接連接到 USB 感測器。

直接在 PC 上執行量測

Keysight BenchVue 軟體支援 U8480 系列功率感測器。 有了 Benchvue 軟體，您無需編寫程式便可輕鬆控制功率錶，以便進行資料紀錄，並透過多種顯示選項顯示量測結果。 您只要將感測器連接到安裝了 BenchVue BV0007B 功率錶/感測器控制與分析應用軟體的 PC，便可立即執行平均功率量測和分析。
