ELECTROMAGNETIC FIELD INTENSITY DISTRIBUTION DETECTOR, AND ELECTROMAGNETIC FIELD INTENSITY DISTRIBUTION DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To determine a maximal value of suitable separation frequency in evaluating the malfunction or performance degradation of a sample apparatus.;SOLUTION: A frequency identifying section 14 determines the coincidence between the electromagnetic field intensity distribution when the frequency of a test signal stored in an electromagnetic field intensity distribution storage section 13 is a reference frequency f and the electromagnetic field intensity distribution when the frequency of the test signal is a frequency (f+n*Δf) other than the reference frequency f. The frequency identifying section 14 identifies a frequency most separate from the reference frequency f, of the frequency (f+n*Δf) of the test signal corresponding to the electromagnetic field intensity distribution whose coincidence with the electromagnetic field intensity distribution when the frequency of the test signal is the reference frequency f is higher than a predetermined value.;COPYRIGHT: (C)2014,JPO&INPIT
