Interface-Based Communication

Communicate with instruments using interfaces

With interface-based communication, the basic workflow comprises common steps regardless of interface type. First, you create an object of the interface type you are using to connect to the instrument. Then, you can set connection and communication properties based on your workflow and instrument configuration. Next, write data to and read data from the instrument. Finally, when you are done working with your instrument, disconnect from it by clearing the object from the workspace.
