Abstract
There is provided a measuring apparatus for measuring a signal-under-test, having a comparator for sequentially comparing voltage values of the signal-under-test with a reference voltage value fed thereto at timing of strobe signals sequentially fed thereto, a strobe timing generator for sequentially generating the strobe signals placed almost at equal time intervals, a capture memory for storing the comparison result of the comparator and a digital signal processing section for calculating jitter of the signal-under-test based on the comparison result stored in the capture memory.
