How Do I Sample From Multiple Channels Simultaneously Using DAQ Assistant

Updated Apr 2, 2025

Issue Details

I am using DAQ assistant and I would like to read data from multiple channels simultaneously. How can I accomplish this?

Solution

Channels using the same measurement mode can be combined into a single DAQ Assistant task by selecting multiple channels on the configuration window. Each measurement type will need to have its own DAQ Assistant to handle that type. The build Array function can be used to combine data from the different DAQ Assistants into a single data set.

Additional Information

DAQ assistant is meant to be used primarily for prototyping. The recommended method for sampling from multiple channels is to use the full DAQmx driver and to use channel expansion.
