回复： Analog Input and Output

[fdfdfdf]

Hi Everyone:

I got a question for the example of Analog Input and Output that comes with 5640r.

I try to use the single Tone mode to generate sine waveform, it works really fine when I use scope to catch it.

However, the problem is when I change the sine waveform to square or triangle waveform, I can not get those waveform correctly.

For some reason, it still gives me sine waveform.

I am new to Labview, so sorry to ask this fundamental question.

Thanks for your help.

Hi fdfdfdf,

What exactly is the example you've used? Any screenshot available? And has the waveform ever changed after you changed the waveform from sine to square/triangle?

HI, Sentica:

I am using the example called ni5640R Analog Input and Output

I changed the sinewave under Single Tone to square waveform.

Thanks

The waveform is changing slightly, but it is still a sine waveform not square or triangle waveform.

Thanks

Try immediately replacing Sine Wave.vi with Square Wave.vi in the "Single Tone" branch after reopening the VI without running it. Also make sure the input values are default.

Keep me updated
