Electromagnetic field measurement device , electromagnetic field measurement method and the electromagnetic field measurement control program used in the measuring device

摘要

The electromagnetic measurement equipment which measures the electromagnetic field in high sensitivity vis-a-vis the minute territory and the like where the electronic device is mounted on high density is offered. As for the electromagnetic measurement equipment which depends on this invention, amplitude level of the same signal light (pf) is adjusted due to the fact that the angle for the deflection aspect of signal light (pf) on the basis of the amplitude level control signal (eb) which from the arithmetic and control unit (40) is given by the analyzer (34), is adjusted. It can give to the analyzer (34) the amplitude level control signal (eb) by the arithmetic and control unit (40), on the basis of the spectrum (ea) of the electric information (ed) which with RF spectrum analyzer (39) was measured. In the receptor (38) ratio of amplitude level of the carrier and the side band which are included in the signal light (pH) which incidence is done is controlled to one fixed-command.
