Abstract
The present invention relates to an electro-optic sampling oscilloscope. This electro-optic sampling oscilloscope carries out measurement of measured signal by using an optical pulse generated based on a timing signal generated from a timing generation circuit synchronous with a trigger signal, providing: a timing generation circuit comprising a fast ramp circuit that outputs a ramp waveform using said trigger signal as a trigger, a slow ramp circuit that increases stepwise and sequentially the output value according to said timing signal; a comparator circuit that compares the output of said fast ramp circuit and the output of said slow ramp circuit and outputs the results of this comparison; and a gate circuit that limits the output of said comparator circuit by closing a gate only when the output of said comparator circuit is unstable based on the input trigger signal and timing signal.
