Method for measuring the waveform capture rate of parallel digital storage oscilloscope

摘要

The present invention provides a method for measuring the waveform capture rate of parallel digital storage oscilloscope. On the basis of double pulse measurement, and in consideration of the asymmetry of acquisition and the refreshing time of parallel DSO, the present invention provides a step amplitude-frequency combined pulse measurement to measure the time for waveform acquisition and mapping T_map, the number of captured waveforms before LCD refreshing W_acq and the dead time caused by LCD refreshing T_DDT, and then calculates the measured average WCR of parallel DSO, according to the measured data, so that the WCR of parallel can be measured.
