64 IEEE 1394 Fundamentals and Interface Overview Chapter 4
Using the HP E8491A
with the HP E1406
Command Module
Though not a common configuration, the HP E1406 command module can
be used in the same mainframe as the HP E8491 to provide HP-IB access to
instruments. In this configuration, however, the E8491A must be the
mainframe’s resource manager.
The HP I_O
Libraries
The software required to use the IEEE 1394 interface in a VXI system is
contained in the HP I_O Libraries and HP VXIplug&play Drivers. The
software supports the Windows 95 and Windows NT platforms.
The software “stack” shown below shows the relationship of the
VXIplug&play drivers to HP VISA/ SICL, to the host adapter drivers, and
to the VXI instruments. Notice that Hewlett-Packard’s implementation of
the IEEE 1394 interface requires HP VISA and will not work with the VISA
supplied by other vendors.
Most application programs are written using the instruments’
VXIplug&play drivers. The plug&play driver functions make subsequent
calls to the VISA functions and so on. Message-based instruments can be
programmed at the HP VISA / SICL level by embedding SCPI commands
in the HP VISA / SICL functions.
