50 Keysight CXG, EXG, and MXG X-Series Signal Generators Programming Guide
Using IO Interfaces
Using LAN
Using 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. It is intended to provide GPIB capabilities such as SRQ (Service
Request), status byte reading, and DCAS (Device Clear State) over a LAN
interface. This protocol is a good choice for migrating from GPIB to LAN as it
has full Keysight VISA/SICL support.
Configuring for VXI–11
The Keysight IO library has a program, IO Config, that is used to setup the
computer/signal generator interface for the VXI–11 protocol. Download the
latest version of the Keysight IO library from the Keysight website. Refer to the
Keysight IO library user manual, documentation, and Help menu for
information on running the IO Config program and configuring the VXI–11
interface.
Use the IO Config program to configure the LAN client. Once the computer is
configured for a LAN client, you can use the VXI–11 protocol and the VISA
library to send SCPI commands to the signal generator over the LAN interface.
Example programs for this protocol are included in “LAN Programming
Interface Examples” on page 115 of this programming guide.
It is recommended that the VXI–11 protocol be used for instrument
communication over the LAN interface.
To communicate with the signal generator over the LAN interface you
must enable the VXI–11 SCPI service. For more information, refer to
“DHCP/Auto-IP LAN Configuration Sequence” on page 45.
If you are using the Windows NT platform, refer to “Windows NT and
Keysight IO Libraries M (and Earlier)” on page 19 for information on using
Keysight IO Libraries versions M or earlier to configure the interface.
For Keysight IO library version J.01.0100, the “Identify devices at run–
time” check box must be unchecked. Refer to Figure 2-3.
