LAN Interface
A LAN (TCP/IP) interface is a logical collection of properties that can apply to remote interfaces and instruments. A LAN interface does not directly represent physical devices. Several physical devices may be auto-discovered or manually added on a single LAN interface. In this case, the interface properties apply to all related devices.
The default LAN interface is TCPIP0. Changing properties of this interface (such as timeouts) will apply to all its associated LAN instruments. To maintain two or more groups of instruments with different interface properties, add a new LAN interface, and then add instruments specifying the interface whose properties you wish to apply to that instrument.
Adding new interfaces offers several advantages, including enhanced organization of instruments within the view, the ability to utilize various protocols, and greater control over timeout values.

A local area network (LAN, also known as Ethernet) provides instrument connectivity over distances and allows sharing of instruments among multiple users and multiple PCs. Ethernet LANs are almost universally available; they support data rates of 10 to 1000 megabits/second, and they use inexpensive cables and connectors. Many instruments have LAN interfaces built-in; for those that do not, you can use the KeysightE5810B LAN/GPIB/USB Gateway. LAN is a recommended method to connect instruments together in applications such as new test systems.
You can connect your instruments to a private LAN or to a site LAN.
- A private LAN is set up specifically for your use in connecting your instruments. Typically, you will be the administrator of the private LAN, and you will control connections, cabling, and addressing. Your PC and all instruments are connected via a networking switch or router that isolates them from your site LAN. You can think of a private LAN as just another type of bus for your test system, like GPIB or USB; the private LAN is used only by your test system. You should use a private LAN if you want total control of your network and instruments, or if it is important that your test system achieve maximum throughput.
- Your site LAN is the network you use to connect with other PCs, printers, and devices in your work group. Your PC is probably already connected to the site LAN; you use the site LAN to connect to your intranet or to the Internet. If you want to share instruments with other users, or if you need access to instruments across an intranet or the Internet, you can use your site LAN. You may need to work with your IT department to put your instruments on the site LAN.
