VXI Interfaces Overview
As shown in the following figure, a typical VXI (E8491) interface
consists of an E8491 PC Card in a Windows PC that is connected to an
E8491B IEEE-1394 Module in a VXI mainframe via an IEEE-1394 to
VXI cable. The VXI mainframe also includes one or more VXI
instruments.
Example: VXI (E8491B) Interfaces
The VXI interface system in the following figure consists of a Windows
PC with an E8491 PC card that connects to an E8491B IEEE-1394 to
VXI Module in a VXI Mainframe. For this system, the three VXI
instruments shown have logical addresses 8, 16, and 24. The
Connection Expert utility has been used to assign the E8491 PC card a
VISA name of VXI0. VISA addressing is as shown in the figure.
For information on the E8491B module, see the Agilent E8491B User’s
