Hi, I have downloaded the hp 4145B.dll and i can run each of these VIs separately to operate my device. But I want the data to be written in a text file or into an excel spreadshit. There is an output Vi file in the library however that does not write the data to any file. I am very new to labview so could anyone please tell me how to capture the X and Y data from the device and write into a text file?
