how can I record multiple signals for a long period of time?

Hi, everyone

I am new at labView I just recentlyl started using it. Right now I am working on this assignment

that I have to display en record six different signals comming up from a DAQ. so basically What I did

for my IV is placing a whileloop. Inside the while loop I set up the DAQ assistant and then I send that

to a split signal function in order to split the signas that are comming from the DAQ ( so those signals

are EMG1,EMG2, blood flow1, blood flow2, blood pressure, and AM stimulation) after I split the signals

I send each individual signals to a waveforme graph, but my problem is that I need to record those individual

signals for a long period of time every second for about 8 hours. so it will be really helpfull if someone can

guide me through this. Thanks

Regards

Record as in recording the data to a file?

 

Have you tried searching?  Looked on the File I/O palette?  To get started quickly, you could use the Write Measurement File Express VI on the File I/O.

Hi,

With your while loop, you'd better use low-level VIs to write your data to a file. Please see attached...I've used text file function but if you need ta save a large amount of data, you may need to use binary file functions instead (nearly the same way to perform this whatever you chose text file or binary file function).

Best,

J.

Hi - please visit our Biomedical User Group located HERE - lots of good information about using LabVIEW in biomedical applications, plus information on the free download of our Biomedical Starter Kit.

 

Thanks!
