ABSTRACT:
A measuring apparatus that measures a characteristic of a transfer circuit includes: an electrical signal sending section that transmits a sending signal; a current to light converting section that converts the sending signal into an optical signal; an optical signal transmitting section that transmits the optical signal; a photo-electric converting circuit tat converts the optical signal into an electrical signal; a level measuring section that compares the intensity of the electrical signal output from said photo-electric converting circuit and a predetermined reference level to detect a data value of the electrical signal; an electrical signal receiving section that detects a data value of the electrical signal; and a timing controlling section that controls latch timing at which said electrical signal receiving section detects the data value of the electrical signal.
