Tokyo Electronics Trading Co., Ltd. (TET) is a small, but high tech electronics company base upon the high speed pulse technology as well as additional know how. We design, build, import and sell variety instruments and automated systems those measure or analyze analog or digital signals with high precision. Since established in 1977, we have been contributing for many customers to develop electronics components and semiconductor devices.

Technologically, TET started from sales and maintenance of high performance pulse generators and other instruments manufactured by E-H Research Laboratories in the USA. Today, we produce fully automated ESD and Latch-up Test Systems, CDM Test Systems and other tailored systems.

Not only design and sell products, but we may contribute to improve the scheduling of your development projects by our activities such as maintenance, making applications and consulting, because we are professional of electronics measurements.
