I have problems with triggers

[jcastan]

Hi,

I want to do this: When a signal reaches an established level, the trigger act and begins the recording data during a time.

So, im trying to use a trigger fixing a positive value. But the recording data begins when I start the measurement.(clicking the run button).

How could I do what i wish?

Other question.

Is possible to record data when the signal reaches a level and stop the recording when the signal value dicrease? How can I do that? 

Thanks a lot.

Hi jcastan,

The answer to the first of your answers is yes, you should be able to do that.

Try to configure your task as it appears in the attached snapshot "trigger.jpg", just change the triggering value according to your application. It should work, in my case I've wired a square waveform to channel no.1 and I am using it to trigger the task.

The answer to your second question is a litlle bit more tricky, first try to add a Limit test (see snapshot "test.jpg"). It is a quite straight forward implementation but it may work, in my simple case it showed to behave correctly. Test it and let me know if it worked.

Hope you found it helpful.

Best.
