PXIe-6124 DAQ

[ngTenn]

Hello,

I have a PXIe-1071 chasis with a PXIe-6124 DAQ card.  My goal is to obtain 2 channels of continuous data at a rate of 2.5MS/sec/channel for some time less than 1 minute.  I would also like to have the GUI viewing/comparing/plotting the channels in near real-time.  I have done this before with a scope card taking chunks of data, but that left undesired holes in the data.  Please advise on the optimal software approach for this application.  

Thanks,

Nick

You could use DAQmx software events in a producer loop like in this example:

Have two consumers:

1 To compare / data process

2 To Graph

Look at http://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/memory_management_for_large_data_sets/ for displaying data.
