Troubleshooting help:
You can verify that you can open a socket connection to your instrument by using telnet:
telnet <IP address> 5025
Characters typed from your keyboard will not be echoed from the instrument and the SCPI
prompt will not be given. However, you will be able to send commands and query the
instrument. For example, you can type *idn? and the instrument identification string will
be returned.
Using SICL LAN to Control the Instrument
SICL LAN is a LAN protocol using the Standard Instrument Control Library (SICL). It
provides control of your instrument over the LAN, using a variety of computing platforms,
I/O interfaces, and operating systems. With SICL LAN, you control your remote instrument
over the LAN with the same methods you use for a local instrument connected directly to
the controller with the GPIB. More information about SICL LAN can be found in the HP
Standard Instrument Control Library user’s guide for HP-UX, part number E2091-90004.
Your instrument implements a SICL LAN server. To control the instrument, you need a SICL
LAN client application running on a computer or workstation that is connected to the
instrument over a LAN. Typical applications implementing a SICL LAN client include
• HP/Agilent VEE
• HP/Agilent BASIC
• National Instrument’s LabView with HP/Agilent VISA/SICL client drivers
The SICL LAN protocol is Agilent’s implementation of the VXI-11 Instrument Protocol,
defined by the VXIbus Consortium working group.
Older versions of National Instruments’ VISA does not support the VXI-11 Instrument
Protocol. Contact National Instruments for their latest version.
SICL LAN can be used with Windows 95, Windows 98, Windows NT, and HP-UX.
Your instrument has a SICL LAN server to emulate GPIB over LAN, but it cannot be used to
control other connected GPIB instruments.
Collecting SICL LAN Set-up Information
Before you set up your instrument as a SICL LAN server, you need some information about
your instrument. The “value” of the following parameters is used to set up your VISA/SICL
LAN client application:
