NI6221 fast sampling

[GeFi57]

Hello,

we are using a PCI-6221 DAQ-Board, MSVS2010 C#, DAQmx-Driverfunctions, no measurement studio.  The sampling of the slow analog channels runs very well by a sample each 50 msec. . But now we have to measure a fast voltage signal. The neasurement  takes about 50msec, the sampling rate has to be about 100Hz,, the trigger has to be  by a voltage level and/or by my software.

How can we do it, which are the functions of the DAQmx ?

Hi GeFi57,

if you installed the support for text based programming language along wiht the installation of DAQmx you should have plenty of C# .NET examples. See screenshot here:

I attached here also a zip file with the code for a finite acquisition with analog trigger.

Best regards
