Hello, I am acquiring data at 100 MS/s through DAQ card. They are pulse traces received back. Now when i use write text file or other standard file i/o; I get lag and some samples are missed. Similar is the case with TDMS applied in the same loop. Can some one please guide me how to log such data. Its generated inside a while loop. Thanks

Will this not be same as writing in the while loop of data acquisition? Thanks TBH: It should not matter because the benefit of the Producer/Consumer is the Queue in between the loops. The Queue is a buffer that allows the DAQ (Producer loop) to run full speed and the Consumer loop can then dequeue, analyze, display, and save data to disk without affecting the speed of the DAQ (Producer loop). I suppose if you were collecting large amounts of data you could still run into memory issues if the Queue size gets out of hand before it can be written to disk. So in that case faster formats like TDMS could be useful.

Dear RTSLVU

Thanks for introducing the producer consumer idea.

It worked.

I passed my acquisition data into the producer queue, and saved the data in the consumer loop using TDMS.

Thanks community!!
