Data Acquisiton

[shifat046]

I am using NI Virtual bench for acquiring current signals. Every time I export data, only 1200 data points are saved. I tried changing Time/Div and other options too.

Is there any way to save a large amount of data? Like 100,000 data points using Vitrualbench? Thank you.

Hello again 😄

The VirtualBench application exports the data visible in the graph, and that data is typically decimated so that there is 1 sample for every pixel. This is one of the optimizations we use to maximize the scope's update rate.

To save the full acquisition, you need to use the driver API, and NI provides a sample LabVIEW program as well as a sample C program in C:\Users\Public\Documents\National Instruments\VirtualBench ANSI C Examples . For additional information on configuring a C project, see this thread.
