Remote frequency calibration experiments between NMIJ and foreign site
- Toward to establish a convenient calibration system -

National Metrology Institute of Japan (NMIJ) of AIST and Yokogawa Electric Corporation have successfully performed a remote frequency calibration experiment between NMIJ in Tsukuba Japan and Yokogawa Electric China in Suzhou, China.

The experiment shows that a remote frequency calibration system will be established in near future. The system will provide quick calibration services to Japanese & other companies in foreign countries.
