PROBLEM TO BE SOLVED: To obtain a simple and highly accurate analog signal adjusting device which is easy to operate whereby a plurality of synchronized analog signals and inverted signals thereof are alternately outputted on a time shared basis by exchanging by means of a switch means. SOLUTION: A SIN wave and a COS wave which are two synchronized analog signals are inputted to input terminals 11, 12. When the contact points of switches SW1, SW2 are switched to sides (a), the SIN wave is inputted to an X input terminal of an oscilloscope OSP and the COS wave is to a Y input terminal thereof. When the contact points of switches SW1, SW2 are switched to sides (b), the SIN wave and COS wave are respectively inverted 1y inverting amplifiers V1, V2, then applied to the X, Y input terminals of the oscilloscope OSP, respectively. In this condition, when the switches SW1, SW2 are switched in an adequate speed, a Lissajous pattern formed of the SIN signal and COG signal and a Lissajous pattern formed of the inverted signals thereof are indicated on the oscilloscope OSP on a time shared basis to be adjusted.
