Issue Details

I am considering using the PXIe-4302, an analog input module, for both voltage and temperature / thermocouple measurements. From the device's specifications, I saw that this device can do both, but I'm not sure if this can be done simultaneously. Can voltage and thermocouple measurements both be taken at the same time on the PXIe-4302?

Solution

The voltage and temperature measurements can both be taken on the PXIe-4302 in one program. After simulating this device and adding two separate input tasks for each measurement type on different channels, you can evaluate what this can look like using DAQmx shipping examples. You just need to ensure that you are using the same time base for the measurements. An image of what this can look like is found below:
