testsignalvorrichtung to produce a maximum zeitfehlertestsignales without influence by low pass filter

摘要

A setting unit (23) sets holding time for holding the upper limit value and lower limit value of the repetitive waveform of signal over a predetermined time, so that signal cycle having shortest cycle with several signals generated by signal generating units (24(1)-24(n)) is longer than predetermined time corresponding to the predetermined high-cut characteristics of low-pass measuring filter.
