How to acquire pretrigger data?

[dragonos_de]

Hi guys,

I need the following:
- acquire pretrigger data
- read pretrigger data

I'm using .NET 2.0 (C#).

Is there any example that describes it?

I found only ReferenceTrigger - but no way how to get the pretrigger data.


best wishes,
Alex

A little bit more information:

I've to trigger levelbased (ai0 ... aiX above/below a specified level) or to a digital trigger (PFI2).

Pretrigger data has to be recorded and the actual value should always be displayed.

Is this possible within .NET and DAQmx?

Hi Alex,

Did you look into the NI-DAQ™mx C Reference Help? You can find it in the Start Menu at the National Instruments»NI DAQ folder.
