Analog ouutput duration

[marius246]

Hi everyone,

I'm generating a waveform with a sample rate of 50000 Hz and 200000 data points corresponding to a signal of 4s. However, the signal I get has a duration of about 3.8s instead and have no idea why that is. I'm creating a waveform with the 'Sine Wave.gvi' connected to 'Build Waveform' to feed the hardware. I verified the number of data points by displaying the signal output graphically and the 'true' temporal duration with an oscilloscope.Has anyone an idea why these two don't match?

I would be very happy about some ideas/suggestions!

Thanks!

Hi marius246,

Could you post your code and pictures demonstrating how you've verified that the signal is not as long as you expect? This would help me and other users better identify why you're experiencing this behavior.

Sure! Attached you"ll find a picture of the code, the front panel and the signal, measured with an oscilloscope. Unfortunately, I can't access internet right now with the computer I run the code from, that's why I could only attach pictures of the code. I hope you can see it sufficiently well.

Best, Marius
