outputting finite and continuous samples on the same DAQ board and same task

[dzhuang]

Hello i am using a pxi6133 card and i would like to output two waveform graphs, one showing continuous sampling and the other showing finite sampling triggered by an analog edge trigger. I was wondering if this is possible to have 2 graphs of different sampling modes in the same task.

-Thanks

Hi,

One task can only have one sample clock type.  You could, however, acquire continuously and use a software trigger to trigger the data that is acquired.  There's an example that uses this software trigger during continuous acquisition.  It can be found at "Hardware Input and Output >> DAQmx >> Analog Measurements >> Voltage >> Cont Acq&Graph Voltage-Analog SW Trigger.vi"  In the example finder. 

You can modify the code so that it is continuously acquiring and displaying the data and triggering on each iteration.  It doesn't work perfectly, but it's a place to start.

If I'm not understanding exactly what you are trying to do, please let me know.
