Simultaneous analog acquisition and generation of one TTL pulse

[ATsch]

Hi

I need to acquire 1 s of analog data. 100 ms after the start of the acquisition, I would like to send one TTL pulse (digital output) to start an other device.
I'm using LabVIEW 2011 and could not find an appropriate simple example.
Thanks a lot for your help.

Everything depends on the hardware you are using. So what device are we talking about?

How precise does the 100msec need to be?

Hi Christian

I'm using a PCI 6071E.

Hi Mike

around 1 ms is fine.

Have a look at the example "Gen Dig Pulse-Dig Start.vi". Use this example in combination with your Analog Acquisition Task to fire the pulse.

Use the "Initial Delay" parameter to specify the 100ms.

As Trigger Source use "DevX/ai/StartTrigger", where X is your Device, e.g. Dev1.
