Title: Method and apparatus for measuring current waveform
Inventor: SASAKI HIDEKI
IPC: G01R19/00
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To ensure sufficiently an excellent measurement precision by performing measurement, setting the shortest distance between the magnetic field sensor and a wiring pattern to a maximum allowable value or less shorter than the length of the wiring pattern sufficiently, and shorter than the wavelength of a signal as well. SOLUTION: The frequency band Fr of a waveform to be measured is determined by the frequency bands of an oscilloscope (a voltage measuring element) 4 and a magnetic field sensor 2, and on the basis of this a magnetic field measuring distance h1 is found by h1=3×10<8> /(Fr ×6). Next, a magnetic field measuring distance h2 is found by h2=L/2 from the length L of a pattern 8 to be measured. And the shorter one out of both magnetic field measuring distances h1, h2 is used as a distance h0 (a maximum allowable value) for measuring the waveform of a magnetic field, and the magnetic field sensor 2 is arranged at this distance h0 using an actuator 3. And from a magnetic field waveform measured a current waveform is found using an approximate expression.  Consequently, it becomes possible to perform indirect measurement with a sufficiently excellent measurement precision, even when it is impossible to make a measuring distance from the wiring pattern 8 shorter because of mounted components.
