Abstract
A near-field measurement system includes a measurement probethat receives a radio signal that is transmitted from an antenna under measurementat a plurality of measurement positions included in a predetermined scan range, a frequency converterthat frequency-converts a frequency of the radio signal to a desired frequency, a timing processing unitthat generates a timing signal for starting measurement of an amplitude and a phase of the radio signal from a trigger signal output from a transmission devicein synchronization with transmission of the radio signal, and an amplitude and phase calculation unitthat acquires a radio signal frequency-converted by a frequency converterand digitized by an A/D converteron the basis of a timing signal for each measurement position and calculates an amplitude and a phase in a near field of the acquired radio signal.
