Company information
Our company was founded in 1975 as "a company that manufactures noise testing equipment to reproduce the malfunction of electronic devices" at a time when the term "EMC" began to be used as the phenomenon of malfunctions associated with the spread of computers was becoming a social issue. Since then, we have provided products that reproduce (output/measure) electrical noise phenomena such as electrostatic discharge, high current phenomena during lightning strikes, transient phenomena in automobiles, and visualization of electromagnetic fields, as well as contracted EMC testing services (contract testing site "Test Lab Funabashi") and technical materials such as "NoiseKen News" (formerly Technical Reports) and "Testing Method Guidebooks," leading to the adoption of our brand "NoiseKen" by over 5,000 customers in dozens of countries worldwide. Based on our history and achievements, we will continue to challenge the reproduction of electrical noise, which is the foundation of our establishment, while also responding to changes in the nature of testing and measuring instruments, including automation and simulation, aiming to be "a company that makes EMC testing easy for our customers." In doing so, we intend to contribute to EMC and noise countermeasures and create a "NoiseKen" that is recognized as a lasting presence by everyone.
