GPIB-VXI Interfaces Overview
As shown in the following figure, a typical GPIB-VXI interface consists
of a GPIB card (82350 or equivalent) in a Windows PC that is
connected via a GPIB cable to an E1406A Command Module. The
E1406A sends commands to the VXI instruments in a VXI mainframe.
There is no direct access to the VXI backplane from the PC.
