How to display trigger line signal along with analog input signals

[Sastra]

Dear all,
How can I do to get trigger signal line together with 3 analog signals using PCI-6024E.
The frequency of the analog signals are 400 Hz. All of the 4 signals are respected to the same reference.

I would be very happy if I can get to a link to a source code.

Just a thought, can't you just connect the trigger signal to an analog input of the card?
After all, just like watching BW movies on a color TV, there is no problem in connecting digital signals to an analog input. But check first to see if there is no problem with the voltage-levels.

Good luck, Patrick de Boevere

How about configuring the board to trigger from one of the analog inputs?

Sastra;

If the trigger signal you need is TTL type, you can use one of the general purpose counters available at the board to do that.

You just need to configure the counter to do retriggerable single pulse generation, and have the reference signal that clocks the analog inputs routed to the gate of that counter. That will generate a pulse at the event of an active edge at the counter gate.

Hope this helps.

Thanks Filipe for your comment and suggestion.
Actually I have one digital signal (TTL-type). I want to use this TTL signal as a reference timing measurement to the other 3 analog inputs. Can you suggest how to get all of those signals and display at once after acquisition.

Maybe Labview has an example of this kind of problem?, Please let me know how can I get the link of this solution.

Sincerely yours,
Sastra
