2 analog input tasks with a same card (daqmx)

From what I have read it is not possible to have two seperate tasks for same type of input/output in the same card that has different sample rates, which make sense as there is only one clock. But is it possible to have 2 analog tasks with the same sample rate triggered at different overlapping times for the same card?

If not is there other way of capturing two different analog signals with the same card at overlapping times, but different starting points (without just acquiring data for whole duration and discarding unneeded data)?

Hello DeXodus,

 

only one AI taks can be triggered and started on the PCI-6224.

 

An option was to acquire all the signals triggers and analogs inputs with the analog part and in a postprocessing step the acquired signals can be filtered where the trigger occoured and the read the samples from the analog channel..

 

Hope it helps.

best regards
Alexander
