摘要
高精度多功能时间校验仪是利用高精度GPS授时模块产生标准信号来驯服本地的压控恒温晶振,保证给系统提供高精度、高稳定度的时钟信号。在测量的方法上采用等精度测量法消除±1的测量误差,利用时间间隔测量法提高测量精度。同时选用荧光点阵显示屏,进行图文显示,具备了良好的人机接口。仪器还提供测量频率、周期、相位、日计时误差等功能,扩展了仪器的应用范围。
The high-precision muhi-function time calibrator is the use of high-precision timing GPS module to generate the standard signal to tame the local oscillator voltage thermostat, available to the system to ensure high precision and high stability of the clock signal. In the methods of measurement such as measurement accuracy ± 1 to eliminate the measurement error, using the time interval measurement method to improve measurement accuracy. At the same time, selection of fluorescent dot matrix display, the graphic display, with a good man-machine interface. The apparatus also measured the frequency, period, phase, time errors on other functions, the expansion of the scope of application of the apparatus.
