Configuring I/O Interfaces
Configuring VXI Interfaces
Example:
Configuring
GPIB-VXI (E1406A)
Interface
The GPIB-VXI interface system in the following figure consists of a Windows
PC with an 82350 GPIB card that connects to an E1406A Command Module
in a VXI Mainframe. The VXI mainframe includes one or more VXI
instruments. When the IO Libraries were 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.
The IO Config utility has been used to assign the GPIB-VXI driver a VISA
Name of “GPIB-VXI0” and to assign the 82350 GPIB card a VISA name of
“GPIB0” and SICL name of “hpib7”. With these names assigned to the
interfaces, the VISA addressing is as shown in the figure.
For information on the E1406A Command Module, see the Agilent E1406A
Command Module User’s Guide. For information on VXI instruments, see
the applicable VXI instrument User’s Guide. See the Agilent VISA User’s
Guide for details on VISA commands.
