ABSTRACT:
An apparatus for calibrating the DC voltage level of measurement equipment supplies a calibration voltage through a DC voltage superposition means to the measurement equipment, detects the voltage level supplied to the measurement equipment, and adjusts the calibration voltage. Therefore, in the high-frequency range, the calibration apparatus can reduce the effect on the measurement accuracy of the measurement equipment and supply a highly accurate calibration voltage to the measurement equipment.
