function generator about arb waveform

[kimisj]

I want to use PCI-5412 to generate arb-waveform with about 100M numbers(not simply repeated ) in about 10 seconds,and the problem is the computer can't support that large number of data, is there any good ideas for me to send them continually by separate them into 100 groups without ending or delay?

The NI-FGEN API allow you to write waveforms in "chunks", exactly because fot he use case you describe. Check your examples and your documentation.

Thanks for your reply.

I want to know whether this card can be used as FIFO or can its memory store the data instead of the waveform.

Because I want to ,for example,1203737823929098776651298 (the number is random and not very regular and about 2M),and have to repeated about 50 periods and each period itself is also random, I mean they are not the same with the former ones. Do you have any good suggestions,thanks.
