- The frequency measurement algorithm can accurately track the system frequency by adjusting the amendatory coefficient in real time according to the error of the original Fourier frequency measurement algorithm. 测频算法根据传统傅氏测频算法存在的误差，通过实时调整修正系数的方法，实现了高精度地跟踪系统频率。
- It is measured that the phase noise of mm-wave PLL source is-78dBc/ Hz (Fourier frequency is 1kHz offset carrier 37.4 GHz), spurious is lower than-60 dBc, output power is higher than 40mW. 实验表明;34.;7GHz频率点输出的相位噪声指标(傅氏频率为1kHz时)为-78dBc/Hz;杂散优于-60dBc;输出功率大于40mW。
- It is measured that when Fourier frequency is 1kHz and offset carrier is 92. 7GHz, the phase noise of 3mm-wave PLL source is-75dBc/Hz. Spurious is lower than-55dBc and output power is higher than 10mW. 经测试，92.;6GHz时其相位噪声指标（傅氏频率为1KHz时）为－75dBc/Hz，杂散优于－55dBc，输出功率大于10mW。
