Abstract
An interleaving A/D conversion type waveform digitizer module comprising a means for eliminating spurious components resulting from phase errors according to N A/D converters, wherein the digitizer samples signals continually with a predetermined timing corresponding to a interleaving configuration of the A/D converters, receives signals outputted by a tested device to be tested, converts the signals into digital signals, performs Fourier-transform of the digital signals and performs interleaving.
