USB DAQ-6003

[Pukhtun_Yum]

I am supplying a analogue square wave to a circuit through DAQ-6003 'A0' slot and getting a response signal from the circuit through 'AI' slot. How can i use trigger to take readings so that I get both the 'A0' and  'AI' simultaneoulsy without a time delay ?

Thank you in advance

Please read the manual of your DAQ device, it tells you how to start both AI and AO task using a trigger!

Hi GerdW,

I looked into the documents but did not understand the concept yet. That is why I wrote here for help.

I have attached a program which shows a graph having delay in the input and output from the DAQ. I have read in the document that I have to use PF ports for trigering but I am not using in external hardware for it and want to setup a trigger from DAQ itself.

Can you please see the program and give me some hints ?

You can use a DO pin to output a signal to both PFI pins: this way you can trigger both AI&AO task…

(I'm not sure the USB6003 allows internal routing so you don't need to use a real wire outside of your USB6003 box to connect DO+PFI0/1. Right now I have no device for testing available.)

Where do I have to put the triggering VI in my program and how can I improve the current program ?
