use 2 Data Acquisiton Cards at the same time

[shabu]

We are using PXI chasis for developing a test system. We want to use one card (PCI 6713) for analog output to the unit under test (UUT)and want to use the Dig I/O card to capture the response of the Device under test. currently i have two separate VIs for outputting data to UUT and for capturing response.
can someone suggest a method to integrate this function in one VI. This way we could capture the real time response while the test stimulus is being sent to the UUT.

Thanks

Hello Shabu,

Thank you for contacting National Instruments.

To obtain real-time response while the test stimulus is being sent to the unit under test (UUT), you should place a single point Analog Output (AO) and Digital Input (DI) in the same while loop. In this configuration, you will be sending an AO to the UUT and reading the resulting DI for each iteration.

If this doesn�t solve your problem, please respond with more information. I would also be happy to take a look at your existing code and offer further ideas.

Have a great day.
