Claims

[Scope of utility model registration request]

A potentiometer that attenuates the test AC signal and inputs it to the circuit to be adjusted, a signal converter that converts the AC signal output of the circuit to be adjusted into a DC signal of a magnitude corresponding to the output level, and a signal converter that attenuates the test AC signal and inputs it to the circuit to be adjusted. An automatic attenuator comprising: a comparison amplification section that compares and amplifies a DC signal and a preset reference voltage; and a servo motor that drives a potentiometer according to the output signal of the comparison amplification section.
