Step function with NI 9263 in matlab

[teutopixx]

Hello,

I use the CompactDAQ NI 9263 and want to create a step function.

I would like to use the session based interface in Matlab. In the help directory there is only described how to generate a sine signal.

But what I need is a step from 0 to e. g. 4 Volts. for about 1 second.

Does anyone have an idea how that could work?

Hello teutopixx,

did you think about using the data acquisition toolbox? You can find information about it on the following websites:

Data Acquisition Toolbox 2.18

As National Instruments does not support matlab Code, I cannot give you further input on using matlab (however, other members of the forum might do), but if you have further questions on the toolbox, please feel free to ask.
