Greetings, I am needing to characterize a 10-bit DAC at work using Labview and the NI USB-6363. I have very little experience using Labview and need some direction in completing this task. We are only interested in the INL and DNL. What I have in mind is outputing the 10 binary signal to the DAC. The DAC's output is going to a digital multimeter that will be linked back to Labview via IEEE-488 to USB connection. I have all this setup, I'm just getting lost with how to go about doing this in Labview. Thanks!

Hi joeyjojo, The USB-6363 uses the daqmx library as Jason mentioned. A good overview of the daqmx driver can also be found here. It sounds like you're going to be doing digital generation. Definitely check out the examples that Jason sent you to.... especially the one called write digital channel. Use the DAQmx write VI to configure the device to read a digital 2D U32 NChannel NSample. This will take in a 2-D array where each row corresponds to a new channel and each column is a new sample. You can also look in the daqmx help to get a better explanation of the Daqmx Write. To get to te daqmx help, just go to Help » LabVIEW Help. In the Heirachey, open up VI and Function Reference » Measurement I/O Vis and Functions »DAQmx - Data Acquisiton VIs and Functions » Additional information, and there will be a section in there on DAQmx Write. The best idea would probably be to start coding and let us know if you're getting a certain error. Additionally, if you've never used LabVIEW, it might be looking into for our DAQ and LabVIEW training. Keep us posted how we can help!
