Using the LAN to Control the Analyzer

Using SICL LAN to Control the Analyzer

SICL LAN is a LAN protocol using the Standard Instrument Control Library (SICL). It provides control of your analyzer over the LAN, using a variety of computing platforms, I/O interfaces, and operating systems. With SICL LAN, you control your remote analyzer over the LAN with the same methods you use for a local analyzer 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 analyzer implements a SICL LAN server. To control the analyzer, you need a SICL LAN client application running on a computer or workstation that is connected to the analyzer 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

NOTE

The SICL LAN protocol is Agilent’s implementation of the VXI-11

 

Instrument Protocol, defined by the VXIbus Consortium working group.

 

At the time of the publication of this manual, National Instruments’

 

VISA does not support the VXI-11 Instrument Protocol. However,

 

future revisions of National Instruments VISA will support the VX-11

 

protocol. Contact National Instruments for their release date.

 

SICL LAN can be used with Windows 95, Windows 98, Windows NT,

 

and HP-UX.

 

 

Collecting SICL LAN Set-up Information

 

Before you set up your analyzer as a SICL LAN server, you will need to

 

collect some information about your VISA/SICL LAN client application.

 

The “value” of the following parameters can be found from the front

 

panel System keys. They can then be used to set up your VISA/SICL

 

LAN client application:

 

Emulated GPIB

 

Name

The GPIB name is the name given to a device used to

 

 

communicate with the analyzer. Your analyzer is

 

 

shipped with gpib7 as its GPIB name. The GPIB name

 

 

is the same as the remote SICL address.

 

Emulated GPIB

 

Logical Unit

The logical unit number is a unique integer assigned to

 

 

the device to be controlled using SICL LAN. Your

 

 

analyzer is shipped with the logical unit number set to

 

 

8.
