Hi, I'm working on a VI that will acquire data from a torque transducer and a tachometer, which are both read as analog inputs. I'd like to read the data at a fairly high rate (10kHz) and output the data to a file that has three columns. Column 1 should be the relative time of the acquisition, beginning at zero, and columns 2 and 3 should be the torque and speed data. I've written the attached VI, which acquires the data successfully and displays it on a waveform chart, but I'm a little bit stuck as to the best way to save this data to a file. I've done a lot of reading about various methods, including logging to a TDMS file and streaming using a producer-consumer setup, but I'm confused as to what would be the appropriate thing to do here. Any help or suggestions would be very much appreciated. Thanks, Dan

Hi Bob,

That's a really good point. Thanks for the suggestion.

Thanks! I will have another go at revising my VI today and will post the results.
