The number is the timeout indicator. vi to read 2. To convert it back, use the "To Time Stamp" function. The file should start with a timestamp, indicating when data acquisition began (t0), then. With fast transient operation speeds and high 16-bit measurement resolution, these. I have sampled data at different intervals, processed and export it to a spreadsheet using the "Write to Measurement file" function. In order to measure a pulse, you need to interrupt on a pin change at the start of the pulse, enter the ISR, grab a timestamp (or use the input capture register if using the Timer 1 input capture feature, which is the best way to do it), and exit the ISR. This way you can get any behavior you want. 0 for Windows, including installation and upgrade issues, compatibility issues, and changes from LabVIEW 7. 2 GS/s is featured when working in Dual Edge Sampling (DES) mode.
