Using Sockets LAN
NOTE Users with Windows XP operating systems and newer can use this section to better
understand how to use the signal generator with port settings. For more information, refer to
the help software of the IO libraries being used.
Sockets LAN is a method used to communicate with the signal generator 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
signal generator from which bidirectional communication with a network computer can be
established.
Sockets LAN can be described as an internet address that combines Internet Protocol (IP) with a
device port number and represents a single connection between two pieces of software. The socket
can be accessed using code libraries packaged with the computer operating system. Two common
versions of socket libraries are the Berkeley Sockets Library for UNIX systems and Winsock for
Microsoft operating systems.
Your signal generator implements a sockets Applications Programming Interface (API) that is
compatible with Berkeley socket for UNIX systems, and Winsock for Microsoft systems. The signal
generator is also compatible with other standard sockets APIs. The signal generator can be controlled
using SCPI commands that are output to a socket connection established in your program.
