4 Programming via GPIB and VXI

Example: GPIB-VXI (E1406A) Interface

The GPIB- VXI interface system in the following figure

consists of a Windows PC with an Agilent 82350 GPIB card

that connects to an E1406A command module in a VXI

mainframe. The VXI mainframe includes one or more VXI

instruments.

When Agilent IO Libraries Suite was installed, a GPIB- VXI

driver with GPIB address 9 was also installed, and the

E1406A was configured for primary address 9 and logical

address (LA) 0. The three VXI instruments shown have

logical addresses 8, 16, and 24.

NOTE

For a GPIB-VXI interface, VISA uses a DLL supplied by the Command

Module vendor to translate the VISA VXI calls to Command Module

commands that are vendor-specific. The DLL required for Agilent

Command Modules is installed by the Agilent IO Libraries Suite installer.

This DLL is installed by default when Agilent VISA is installed.
