I have two different devices plugged into a BNC-2110 DAQ board and I need to aquire data from them simulateously. At the moment, LabVIEW will collect data from one instrument and after it is finished that one it will move on to the second one. Please help!
One limitation of a DAQ device is that it can only run one analog input task at a time. This is due to the fact that there is only one analog input timing engine, and this timing engine cannot be shared among multiple analog input tasks. You can however easily combine multiple channels in a scan list under a single task. The requirement here is that you sample from all channels at the same rate and all the channels have the same timing and triggering parameters. You can easily configure a multichannel scan list using the DAQ Assistant, as shown in the following tutorial:
