delayed generation

[Julien_HE]

Hi,

In my system I want to follow these steps:

-put high one output during 20s.

-begin an acquisition.

-put high an other output during 300ms.

My problem:

The second output is more or less delayed but I need to have always the same time between the beginning of the acquisition and the 300ms pulse.

USB-6216

Signal Express Full

I am using 2 timers to put high the 2 outputs.

Regards.

Hi,

I have searched a solution and it seems to be a hardware timing problem.

If I want to have a deterministic trigger I need an external clock ?

How can I use an external clock to make pulses ?

In my "DAQmx-Generate step" the "clock reference type" is greyed out. There is another way to make a deterministic pulse ?

I need to use an analogic output ?

Thanks you for your help.

Regards.

Hello,

What hardware do you use?

Do you want start these step at the same time?
