Measurement Equipment

We offer an All-In-One shielded box for essential EMI testings.
The shielded box is suitable for conducted emission testing and radiated emission testing.
It is purposed for R&D of customer's EUT instead of buying expensive shielded rooms or anechoic chambers.

Dedicated measurement software


There are various disturbance RF signals around us; TV, mobile phones, Wireless LAN. In EMC measurement, those disturbance signals are unnecessary since it disturbs the measurements.
We design and offer various types of shielded rooms not only for EMC tests but also for R&D. Optionally, the shielded room can be combined with sound insulation chamber.
