How to generate independent analog signals simultaneously on one board?

Hello!

 

With my PCIe-6321 board I'd like to generate two independent analog signals at the same time.

 

Meaning:

The first signal has to run in "continuous" mode all the time without interruption.

The second signal has to be generated in "finite samples" mode upon certain software or hardware trigger events.

They may both share the same sample clock.

 

The question:

Is it possible at all to do this on a single I/O-board (such as the PCIe-6321)?

 

I have tried to set that up using the AO0 and AO1 channels. However the second task to be started just returns with an error, stating that required recources have already been reserved by the first one.

 

Would appreciate any hints and ideas.

 

Best regards,

Sebastian

Hi Sebastian,

I’m sorry to tell you that on a  PCIe-6321 only one Task of the same kind can run at the same time.

Best regards,

Roland

Thanks for the info, Roland.

 

That's what I was afraid of. Looks like I'll have to get some hardware add-on.

 

Regards,

Sebastian
