Hi, thanks for reply my question Filipe Martarello.

I have the respetive boards (pci 6025e and pci 6221). My version is Labview 7.0.

I need basicaly to make a program using the Analogic Output of PCI6025E and the Analogic Output and Digital Output (with handshanking) of PCI6221.

I didn´t install the pci 6221 in the computer yet, I need some advice because  I´m only a beginner.

thanks again.

Hi Bruno.

There are a lot of ways that you can use to do that but the measurement needs to start at the same time. In addition, the measurements must share a commom clock for latching data.

You can use Simultaneously Started Measurements - You could use the internal Start Trigger to trigger the analog output to start at the same time as the input acquisiton or have the both operations use either the analog Input or analog Output sample clock.

Using the Measurement Functions you can do all these things.

The links bellow shows you synchronization technics.
