Change your X-Axis scale from absolute time to relative time.

Hi GerdW ,
thank you very much ( you program it works )
i want to aske you if i change the Sine Wave with the cDAQmx it works or note ? (see below )
and what about exporting the signal Data to Excel ?
Thank you for your reply .
Best regards .

Hi Emna,
if i change the Sine Wave with the cDAQmx it works or note ? (see below )
Yes. (Just try it out!)
and what about exporting the signal Data to Excel ?
No problem.
You just need to program it!
(There is a palette full of Waveform functions…)

Hi ,
when i use this program i obtain a graph from 0 seconds to 60 seconds but in the Excel file i only have acquisation from 0 seconds to 20 seconds .
any explanation please .( see below my program )

Hi Emna,
don't use a wait function in parallel with a hardware-timed DAQmx task: let the DAQmx task do the timing!
(DAQmxRead is set to read 50k samples at a sample rate of 50kS/s, so you need 60 iterations to get data for a whole minute…)
Why don't you save the resulting waveform using a Waveform function to a file?

Hi ,
i want your help using DAQmx to stop the acquisation after 60 seconds .
i change the program using extract Waveform to graph and with elapsed time i only end up with Excel file Containe acquisation from 0 Seconds to 20 Seconds . (see below )
