1.2.2 Build Communication Using Sockets/Telnet
Through the LAN interface, VXI-11, Sockets and Telnet protocols can be used to communicate
with the vector network analyzer. VXI-11 is provided in NI-VISA, while Sockets and Telnet are
commonly included in PC’s OS initially.
Socket LAN is a method used to communicate with the vector network analyzer over the LAN
interface using the Transmission Control Protocol/Internet Protocol (TCP/IP). A socket is a
fundamental technology used for computer networking and allows applications to communicate
using standard mechanisms built into network hardware and operating systems.
The method accesses a port on the vector network analyzer from which bidirectional
communication with a network computer can be established.
Before you can use sockets LAN, you must select the analyzer’s sockets port number to use:
Standard mode. Available on port 5025. Use this port for programming.
Telnet mode. The telnet SCPI service is available on port 5024.
