| 抄録 | A frequency standard is used by many companies, laboratories and factories. It is very important to calibrate the frequency standard regularly so that it can trace in the SI units to stabilize quality. The Communications Research Laboratory has been providing frequency calibration services based on the Japanese Radio Law. One of these calibration services is accredited with the ISO/IEC 17025, which is called the ASNITE-NMI accreditation service. Another new calibration service was started in April 2003, which is a calibration service under the Japanese Measurement Law. The calibration services are now only being provided for calibration in CRL's calibration room. However, the demand for a remote calibration system has increased. In this paper, presented are details on the frequency calibration systems and briefly reported is the remote calibration system, which is currently being developed. |
