How do i use NI-7851 to acquire data

[触摸孤独]

it is my first time to use 7851, i want to synchronizlly sample 8 channels datas,but i don't know how to program. Can i use DAQmx? or there is special way.

thank you !

Best wishes.

Take it easy! it's not as hard as you think! NI-7851's driver is NI RIO not DAQmx. furthermore ,first you need to install RIO driver then you can find the example code as belows
LabVIEW's example finder-> hardware input and output->R series-> XXXXX.prj
there are some example codes which you can only do a little change and then be used by yourself.

Sorry that i have another question:

I use TRIG0 to synchronize two 7851R,and it works .But the skew i tested between two cards is 10^2ns,  i want to achieve a skew less than 10ns.

Here is my way to synchronize :

Configure a card as master card, the other one as slave . When i press the Start Button, the master makes TRIG0 high level, the slave waits for the rising edge of TRIG0 at a timeout of -1.

This way works, but I want to know how to make the skew to 10ns or less than 10ns? Or, can the 7851R achieve a skew of 10ns?

What is the typical skew between two card?

Thank you!
