pretriggered plus posttriggered Using DAQmx functions

[bol]

Dear Sirs,

In the propel.vi which is attached, laser is used in the channel Vi0 to start the mechanism of trigging to acquire posttriggered samples from the analog signal in the channel Vi1 successfully. I would like to know what changes I need to do in the block diagram to acquire pretriggered plus posttriggered samples from the analog signal in Vi1?

Thank you for your help.

Oscar Delgado.

Hey,

What you will need is an example for reference trigger, where you can decide the number of pre- and posttriggersamples.

Please use the LV Examplefinder under the LV Help menu and search for reference trigger.

BR, Christian

Hello Christian,

Thank you for your reply. According with your suggestion I found in the examples file of my LV the Cont Acq & Graph Voltage – Analog SW Trigger.vi, which I am using successfully to acquire pre triggered plus post triggered samples.

Thank you for your help.
