定时锁

This board has proper strategy to get the data for power quality analysis, because it uses two chip, six channel analog-to-digital converter and phase locking synchronous technology, which make it able to collect three phase electric voltage and electric current signals in timing sampling and equal-time cycle sampling ways.

并采用了两片六通道高速A/D转换器和运用了锁相同步技术，对三相电压和电流信号能进行定时采样和等间隔采样，这样得到的数据对于下一步电能质量指标进行分析更为合理。

The sampling rate is set up by DSP on-chip high speed counter ,and two 322bit high speed counter s and the counter-controlled electric circuit are constit uted by the external CPLD.

采用 DSP 锁相环技术，将外部输入时钟频率提高5倍，作为时标信号；通过 DSP 片上高速定时器完成采样速率设定功能；利用外部 CPLD 构成两个 32 位高速计数器和计数器开闭控制电路。

M3 featured spring-loaded ejection port cover (which also also act as safety, locking the bolt when it is closed) and crank-type bolt retracting handle at the right side of the receiver.

货币供应M3的功能弹簧式喷射口盖（也还充当安全，锁定时，它已关闭螺栓）和曲柄型螺栓回缩处理在接收器的右侧。
