PXI-6230 analog input trigger setup

[HarveyL]

Hi,

Can anyone point me in the right direction of how to configure the PXI-6230 card to implement 3 of the analog input channels as a digital input trigger? The input to each channel is TTL pulses. I want to have a trigger event on every pulse from any of the three inputs. I'm using LabVIEW 8.5. Any help is appreciated. Thanks.

Hey HarveryL,

I'm not sure it is possible to do this. Can you give me some more details on your application, and why you want to use the analog inputs as a digital trigger? Here is an article on how to use PXI triggers with the analog input and output, perhaps you can adapt that code to your purposes. I'll continue to look into this for you, but any more information you can provide would be appreciated. Have a great week!

Hi John,

Thank you for your reply. I did talk to one of your application engineer over the phone about the subject. I need to use the Discrete Input lines, not the Analog Input lines, for this purpose. He pointed me to a very good solution for my application. Thanks again for your time.

Glad to hear that you are up and running. Have a great week!
