ABSTRACT:
In the A/D converter test method, the square wave pulse as the test signal is supplied to the A/D converter under test; said pulse is converted into the digital signal by said A/D converter; the waveform of said square wave pulse is reconstructed by converting the digital signal outputted from said A/D converter into the analog signal; the rise time of said A/D converter under test is measured from the reconstructed waveform of said square wave pulse; and the dynamic characteristics of said A/D converter is calculated from the measured rise time.
