Abstract
PURPOSE: To secure an error-free measurement of the circuit property by varying the curve showing the reference value in accordance with the output level of the sweep oscillator when the sweep display is given to the frequency response property of the circuit onto the display.
CONSTITUTION: The output of sweep oscillator 8 is divided into two parts through output signal branching circuit 9. One part is supplied to measured circuit 10, and thus the signal corresponding to the frequency response of circuit 10 is turned to the DC signal via amplification detector circuit 11 and then supplied to switch 12. While the other part is supplied to amplification detector circuit 14 to generate the DC voltage proportional to the output level of oscillator 8. This DC voltage is controlled to a proper level through variable resistor RV1 and RV2 of reference voltage generator circuit 15 to be applied to switch 12. Switch 12 is changed over in a smaller period than the sweep period of oscillator 8, and reference level (a) and (c) plus response property (b) are displayed on CRT13.
