3) Telephone Network (TELNET): TELNET is used for interactive, one command
at a time instrument control
For LAN operation, the signal generator must be connected to the LAN, and an IP address
must be assigned to the signal generator either manually or by using DHCP client service.
Your system administrator can tell you which method to use. (Most current LAN networks
use DHCP.)
DHCP Configuration
If the DHCP server uses dynamic DNS to link the hostname with the assigned IP address,
the hostname may be used in place of the IP address. Otherwise, the hostname is not
usable.
Using Sockets LAN
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 predefined SCPI functions (available from
firmware 2.0 upwards) use the socket connection established in your program. Socket
connection is available on port 18.
Using and Configuring VXI-11
The signal generator supports the LAN interface protocol described in the VXI- 11
standard. VXI- 11 is an instrument control protocol based on Open Network
Computing/Remote Procedure Call (ONC/RPC) interfaces running over TCP/IP.
A range of standard software such as NI-VISA or Agilent IO Config is available to setup
the computer/signal generator interface for the VXI- 11 protocol. Please refer to the
applicable software user manual and documentation for information on running the
program and configuring the VXI-11 interface. The program is used to configure the LAN
