Claims

[Scope of utility model registration request]

A phase comparison circuit that compares the phases of two input signals and outputs the difference; two trigger circuits that introduce the two input signals and create trigger signals for each channel; and outputs of the two trigger circuits. 2 to generate a sawtooth wave.
Two sawtooth wave generation circuits and the outputs of the above two sawtooth wave generation circuits are input, and the phase of the output signal of the other sawtooth wave generation circuit is determined based on the output of the phase comparator circuit with one sawtooth wave generation circuit as a reference. A CRT oscilloscope is characterized in that it is equipped with a control circuit that corrects the oscilloscope and generates the two outputs to the CRT via a horizontal axis main amplifier.
