As part of the National Instruments Instrument Control Fundamentals Series, this set of tutorials helps you learn about a common instrument control topic through theory explanations and practical examples.

What You Learn
Ethernet/LAN has become more popular as personal computers started using this bus for network communication. Ethernet/LAN has been used for instrument control for some time now. Many instrument currently support the ethernet bus such as LXI instruments. This set of tutorials and concept documents provides information on how to easily set up and control your Ethernet/LAN instrument to build your test system.

To view the complete list of in-depth instrument control tutorials, please return to the Instrument Control Fundamentals Main Page.


Understanding LAN/LXI for Instrument Control
LAN is one of several busses used to connect instruments to a PC. While there have been many claims that LAN(or other busses) are ideal for all applications, the reality is that each bus has different strengths and real-world systems take advantage of multiple busses in a unified software framework. In particular, LAN is well-suited for distributed applications, but not necessarily for desktop measurements or automated test. This paper will examine LAN in detail as it pertains to instrument control. An emerging standard for LAN-based instruments, LXI (LAN eXtensions for Instrumentation) will also be discussed.
