I use labVIEW and a PCI 4474 (24 bits)to measure a tension in continuous with an extern clockbut there are not extern clock on this card. Can I use the trigger inputas extern clock ?"

The NI-447x devices do not accept external clock due to the delta-sigma converters they use to realize high dynamic range characteristics. Check out this KB which has some more details:

So, no, the trigger input can not be used as a external clock input.

Are you trying to synchronize the NI-4474 with another device? What type of synchronization do you need? What type of device are you trying to synchronize with?
