LAN interface
Many instruments are equipped with a LAN interface that can be connected via a commercial RJ-45 cable to a network with TCP/IP protocol. The TCP/IP protocol and the associated network services are preconfigured on the instrument. Software for instrument control and (for specified protocols only) the VISA program library must be installed on the controlling computer.
Rohde & Schwarz instruments support LAN protocols such as VXI-11, raw socket or the newer HiSLIP protocol. These protocols allow you to control the instrument, for example:
Via C#, Python, Visual Basic programs
Via the Windows applications Word and Excel
Via National Instruments LabView, LabWindows/CVI, MATLAB
The control applications run on an external computer in the network.
Only the IP address or the host name of the instrument is required to set up a connection. This information is part of the VISA resource string used to address the instrument. Several instruments in the same network have different IP addresses, host names and resource strings.
Rohde & Schwarz instruments typically use the following ports for communication via LAN control interface.
LAN protocol | Default port number |
---|---|
TCP or UDP port: 111 TCP port: any port provided by the ONC RPC port mapper (see RFC 1833) | |
TCP port: 4880 | |
raw socket, TCP port: 5025, 5125 | |
TCP port: 2525 | |
mDNS / Bonjour® ("LXI") | TCP port: 5353 |
