Having problem with discontinuity in the waveform

[Kun_Nattapat]

Hi Experts,

I am trying to build a multifunction vi that is able to generate analog waveforms and read them simultaneously using USB-6251 and Signal Conditioning Connector Block Model SC-2345. I plan to add a signal from the sensor to the waveform in the future but that is not the case now. However, when I run the program, it turns out to a small discontinuity in the waveforms which I really have no idea how to fix it. And it is quite unacceptable since it affects the shape of the waveform and its frequency. I attached the file. Any suggestions would be greatly appreciated.

Sorry if my English causes you problems. Thanks in Advance.

You need to learn a little patience. Most of us here are volunteers. Do NOT ask the same question in multiple boards.

It would be better if you can post a screen shot of the discontinuity.

Search the forum for spikes, glitches

Maybe this solves the problem:
