Abstract

PURPOSE: To enable easy and accurate measurement by providing the object of measurement with output from an oscillator of variable duty and frequency at a given wave form timing.
CONSTITUTION: This consists of the object of measurement A which is set so that input signals and output signals are in inverse phase, an oscillator PG of variable duty and output frequency, a counter CTR which measures the output frequency of device A, and an oscilloscope SCP which indicates the input and output signals of device A superposing on a same screen. First, determine the duty of PG so that duties of the input and output signals of device A are differentiated on the screen. Thus the frequency is obtained by the CRT by changing the frequency of PG so that either the rise of the input signal wave form and the fall of the output signal wave form or the fall of the input signal wave form and the rise of the output signal wave form correspond respectively.
