摘要
Abstract
Based on the technique of Dual Mixer Time Difference (DMTD), an 8-channel frequency stabilitymeasurement system has been developed. It realized the measurement of 8-channel 5 MHz and 10 MHz frequencystandards. For 10 MHz frequency, the noise floor is better than 2.0 ×10~(-13)/1 s, 2.5× 10~(-16)/1000 s. It can not only satisfy the internal comparison of time scale ensemble, but also can realize the calibration of normal frequency standards.关键词
