pulse per second

The IRIG-B decoding device can receive IRIG-B code synchronous clock signals and Pulse Per Second ( PPS). The CPLD hardware data acquisition controller ensures the sample time accuracy in the system.

设计了IRIG-B解码器，可以接收IRIG-B同步时钟信号和PPS脉冲信号，并且设计了CPLD硬件数据采集控制控制器保证采样的时间精度；

In this method, the intensity shape of a single shot femtosecond pulse second harmonic is acquired with a linear CCD, using the trigger mode of one trigger per line.

该方法采用线阵CCD作为光电传感器，用单行单次的同步触发方式，将一次触发的fs脉冲激光的二次谐波光强分布采集下来。

Owing to GPS clock, which has no accumulative error, and quartz oscillator, which is very stable, the time counting value is obtained without delay via hardware by combining high speed sampling and PPS ( Pulse Per-Second)-snapping.

利用GPS时钟无累计误差和高精度晶振频率稳定性高的特点，并将高速采样与秒脉冲捕捉有机结合，通过硬件方式无延时地捕捉秒脉冲以获取精确的时间计数值。
