• Select your PC in SystemDesigner.  From the Configuration Pane on the left, scroll down to the Advanced section to selectLaunch NI MAX.  Within MAX expandMy System»Devices and Interfaces»Network Devices to view instruments that are continued to the aforementioned subnet as your PC.  To add an instrument that is not on the local subnet, right-clickNetwork Devices, selectCreate new VISA TCP/IP Resources, and follow the instructions in the magician.

8. The instrument is now configured.

Automate Measurements With LabVIEW NXG

After performing manual/interactive measurements to achieve the results that you demand to test your device, the next step is to perform automatic measurements to reduce measurement time and increase repeatability.

Application Programming Interface (API)

To aid accelerate software development, all instrument drivers follow a consequent programming flow of: Open, Configure, Read/Write, Close. All drivers for NI hardware (for example, PXI modular instrumentat) also follow this paradigm because it is a best practice when programming in LabVIEW NXG.
