NOISE MEASUREMENT PROGRAM, NOISE MEASUREMENT METHOD, AND NOISE MEASURING DEVICE

Japanese Patent JP2023020684

A

To reduce the number of measurement times in near electromagnetic field measurement of a circuit board.SOLUTION: A noise measurement program allows a computer to execute acquisition of time-series data for showing electromagnetic field strength from a measured circuit that is measured during measurement time having a time interval of at least one wavelength of a reference signal in synchronization with a trigger detected based on a signal waveform of a reference signal inputted to a measured circuit that performs switching operation following a reference signal in each of multiple measurement points set near the measured circuit, and extraction of time-series data in a designated section that is designated by time width shorter than time width of measurement time from acquired time-series data, calculation of electromagnetic field strength and phase components at a designated frequency that is designated regarding each of multiple measurement points on the basis of time-series data in a designated section, and output of a plane vector corresponding to electromagnetic field strength and phase components regarding multiple measurement points under a condition of a designated section and a designated frequency.SELECTED DRAWING: Figure 1
