Start and stop triggering

[stumpjumper]

I am struggling with triggering an acquisition using DAQPad-6070E. I acquire one analog channel at a speed about 1000 samples/s. The acquisition should be triggered by an digital signal from an external device. Start triggering on rising edge and stop triggering on falling edge. Each acquired 1D array of data should be inserted into a 2D array.

Does someone out there have a solution how this triggering can be achieved?

Best regards

Jonas,

there is a start trigger but no stop trigger available. I've attached an example created with DAQmx assistant.

The example uses a rising start trigger at PFI0 for starting the data acquisition.
