PICO推出Differential
USB Oscilloscope PicoScope 3425 |
您需要量測 floating 或 non-ground referenced 的信號嗎?
您需要量測 具有50Hz 或 60Hz 的common-mode 雜訊的信號嗎?
有了 PicoScope 3425 differential
oscilloscope 您就不再需要昂貴的 differential preamplifiers 或 probes.
大部份的示波器只能量測 referenced to ground 的信號和只有 “single ended inputs” 但是 PicoScope 3425 具有四個 fully differential inputs 這個功能讓您可以量測那些non- referenced to ground的信號.
因為具備了最大400V 的common mode 和 differential 的範圍. 讓PicoScope 3425 有能力可以量測高壓與低壓的信號. 典型的高壓量測應用包括了抓取switch mode power supplies的波形, Telephone Cables, motor inverters 和 hybrid vehicles. 高阻抗的 differential 輸入 同時也可以量測靈敏的放大器和 bridge type sensors 如 pressure, load 和 strain.
