Abstract

PURPOSE: To improve the accuracy of the overlay measurement by overlapping the input signal and the square wave on the input side of the apparatus.
CONSTITUTION: The input signal A and the square wave signal B are applied to an amplifying means 250 and the overlap signal D is outputted. The signals D and B are inputted to a removing device 256 to remove the signal B, and the input signal A is outputted. The signal A is applied to a horizontal circuit 258 comprising a trigger circuit, a sweep circuit and the like to generate a sweep signal C synchronizing the signal A. Then, the signal D and C are each amplified and fed to the CRT264 as an indication means. In this manner, as the signals A and B overlap before the amplifier, there is no effect due to characteristic change of the subsequent circuit and the sweep signal positively synchronizes the input signal. Thus, the accurate measurement can be done.
