| Abstract: | An optoelectronic technique for transient response calibration of sampling oscilloscopes is proposed.It is based on the femtosecond laser and photoconductive switch theory,and can realize the generation and detection of ultrafast voltage pulses,which serve as calibration signal for sampling oscilloscopes.After the processing such as time base correction,jitter correction and deconvolution,the transient response of sampling oscilloscopes can be calibrated.Furthermore,this technique could get the complete impulse response and step response of sampling oscilloscopes and would be of great significance. |
