Abstract

PURPOSE: To enable precise measurement of characteristics even when the operating frequencies between an instrument and an element to be measured are different each other by providing a frequency divider between the output terminal of the instrument and the element and a multiplying circuit between the input terminal of the instrument and the element.
CONSTITUTION: A frequency modulation signal having frequency f outputted from an instrument 1 is divided in frequency into 1/n by a frequency divider 8, and supplied through a BPF 6 having f/n of central frequency to an element 2 to be measured. The output signal from the element 2 is multiplied by n by a multiplying circuit 9, and inputted through a BPF 7 having a central frequency f to the instrument 1. As a result, no beat occurs since using no local oscillator nor mixer.
