METHOD AND SYSTEM FOR MEASURING NOISE LEVEL OF ELECTRONIC OBJECT TO BE MEASURED

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for determining a noise level of an electronic object to be measured by enabling the discrimination of the noise level even in a case wherein the object to be measured is of a high modulation type. SOLUTION: An apparatus for determining a loudness of the noise (TDUT) inputted to the object (2) is provided with a sinusoidal wave signal source (1) generating a sinusoidal wave signal (Sin) to be inputted to the object (2) and a level meter (3) for measuring a voltage level of the object (2). The level meter (3) is provided with a sign wave power detector device (31) for capturing a sinusoidal wave power level (PSIN) and a noise power level detector device (32) for capturing a noise power level (PNOISE).
