The application of high-speed photo-detector for calibrating oscilloscope

Pengwei Gong, Chuntao Yang, Hongmei Ma, Ming-ren Deng

Open publisher page 1 citations

Abstract

After presenting all kinds of calibrating methods to calibrate the magnitude response and risetime of the digital oscilloscope, this paper describes the method that by using femto-second laser pulse to illuminate high-speed photo-detector ultra-fast electrical pulses with only 10ps risetime which are supposed to calibrate the oscilloscope can be generated. In experiment the 12GHz real-time digital oscilloscope has been calibrated successfully. This method has some advantages such as simple structure, convenience in using and great application potential.
