噪聲測量光探頭

概述

噪聲測量光探頭

It is an “OPTICAL PROBE” that accurately measures the noise electric field and voltage which causes malfunction such as ESD by optical technology without using metal coaxial wire. Since “OPTICAL PROBE” is electrically isolated from the object to be measured, there is no fear that an expensive measuring instrument such as an oscilloscope will be destroyed and safe measurement is possible.

 

Configuration and usage

3 types of measurement are possible by connecting E sensor or V sensor to the controller.

① E-field measurement causing malfunction(Frequency, Phase, Strength) E sensor
② Non-contact measurement of the noise voltage signal of cable/ circuit pattern E sensor
③ Contact measurement of the noise voltage signal of pin terminal of IC/LSI V sensor
