Patent ID: 8140290

Claim:
A transfer characteristic measurement apparatus that measures a transfer characteristic of a circuit under test between input and output, comprising: a test signal input section that generates a test signal by adding together a carrier signal having a prescribed frequency and an additional signal having a frequency that differs from the prescribed frequency, and inputs the test signal to the circuit under test; and a transfer characteristic measuring section that measures the transfer characteristic of the circuit under test at the frequency of the additional signal based on a result from a measurement of an output signal output by the circuit under test, wherein the circuit under test is formed in a semiconductor chip, corrects a signal input to the semiconductor chip, and outputs the corrected signal, the semiconductor chip further includes a sampling circuit that samples the output signal of the circuit under test at the frequency of the carrier signal, the test signal input section inputs the test signal to the semiconductor chip, and the transfer characteristic measuring section measures the transfer characteristic of the circuit under test at the frequency of the additional signal based on the sampling result from the sampling circuit.
