Abstract: As a key instrument in electromagnetic compatibility testing,EMI measurement receiver has been used more and more widely.However,the standard source used for pulse response calibration of this kind of instrument completely depends on imports,and there is no substitute for the standard pulse signal generator in the domestic market.This article introduces a standard pulse signal parameter analysis method for impulse response calibration of EMI measurement receiver.First,we establish the parametric model of the standard pulse signal and perform numerical analysis and simulation to verify whether it meets the requirements of the standard CISPR 16-1-1.After that we build the experimental system,and develop the standard pulse signal generation software which controls the arbitrary pulse signal generator to output the standard pulse signal and compensates it,thus the standard pulse signal which meets the requirements of CISPR 16-1-1 is obtained.The signal can be used to calibrate the pulse response of EMI measuring receiver.
