Continuously Acquire digital have some gap(连续采集数字信号为何有间隙）

[noneofl]

I use the example Finite_Correlated_DI_AI_IntClk to get the digital and analog signal, and save the digital signal into TDM file ,it look like the Picture 1（I have try serveral times,the result is the same.).Compared to the LABVIEW one.Anyone can help me fix the bug?ThankS.

我修改Finite_Correlated_DI_AI_IntClk 例子进行数字信号和模拟信号的采集，记录到TDM文件，打开后发现出现间隙，是程序问题吗（我采集几次也出现间隙）,谢谢
