S87234 Series USB Peak and Average Power Sensor

S87234D/E/F/L USB peak and average power sensor is a diode-detection broadband power measurement instrument based on the USB 2.0 interface, which can realize accurate average power measurement, pulse power measurement with large dynamic range and CCDF statistical measurement analysis. The frequency range covers 50MHz to 67GHz, the highest power accuracy can reach 0.2dB, the video bandwidth is ≥30MHz, and the rise/fall time is ≤13ns.

S87234 series can flexibly expand the power measurement function of electronic measuring instruments and test systems, and is mainly used for field testing, production line testing and system integration.
