(1) need pulse signal source repeatedly to trigger the multiple single pulse signals of output, the amplitude of each single pulse signal is difficult to be consistent completely, there is the unsettled problem of each single pulse signal of pulse signal source output, cause the accuracy of transient electromagnetic field uniformity calibration to reduce;
(2) requirement of pulse signals source output stability causes the cost of transient electromagnetic field generation device higher.
