PXIe-6361 Retriggerable AO

[AKhan]

Can a PXIe6361 be set to retrigger on an analog input (APFI0)?

I have a need to measure a 4mS wide pulse once every second.  The test will run for anywhere from 5 - 60 minutes.

I would like to use an Analog trigger to begin the capture a finite # of samples (1000) on channel AI0 for each pulse.  I have created a task (see attached) to capture a single pulse, can the task be modified to automatically retrigger on a rising edge? Or do I need to create a loop to continually restart the task after each acquistion?

Hardware

PXIe-8133 Embedded controller

PXIe-6361 (qty3)

PXI-5422

Software

Visual Studio 2012

NI-DAQmx 9.7

Thanks in advance

There are several examples for voltage measurements I think that the Cont Acq-Int Clk-Dig Start-Retriggerable might work for you.
