Abstract

PURPOSE: To keep always the reference value in a prescribed-level automatically to display the characteristic, by storing a specific frequency out of input frequencies to a circuit to be measured while updating it at a prescribed period and by using the storage output to control the measure output.
CONSTITUTION: This system is provided with sweep oscillating circuit 11 which applies the input for measure, which changes from frequency f1 to frequency f2 according to time elapse and repeats this change at a fixed period, to a circuit to be measured, device 14 which displays relations between f1Wf2 and response outputs R1WR2 for the measuring input of frequencies f1Wf2, memory circuit 22 which holds response output R0 obtained in specific frequency f0 out of frequencies f1Wf2 while updating it successively at a fixed period, and subtracting circuit 23 which superposes positive or negative-direction fluctuation components of held response output R0 to response outputs R1WR2 uniformly in the negative or positive direction. Then, the subtraction output is displayed.
