Hi,
As per my understanding, you would like to use Data Acquisition Toolbox to control the output of the device and read the data, while using NI PXIe-6739 as analog voltage output.
Note that you can use the Data Acquisition Toolbox to control the output of the NI PXIe-6739 and read the data. The toolbox supports the communication protocol NI-DAQmx, which is used to communicate with National Instruments data acquisition devices.
However, please note that need to install and configure the NI-DAQmx driver to use the NI PXIe-6739 device with MATLAB and the Data Acquisition Toolbox.
For more information on using the Data Acquisition Toolbox to control the output of the device and read the data, please refer to the following documentation:
Hope this helps!
Regards,
Rasmita
