1. Introduction

The help file included with the Agilent E1468 VXIplug&play driver contains
instrument and programming information. This readme file contains
additional information for the Agilent VXIplug&play programmer.

- ---------------------------------------------------------------------------

2. VISA Specific Information

The following topics refer to instances when the driver is used with
different versions of VISA.

2.1 Instrument Addresses

When using Agilent VXIplug&play instrument drivers, instrument addresses must
be all uppercase letters. Implementation of the addressing scheme is
vendor specific and some vendors support mixed cases. However, for
maximum portability, the instrument address should use uppercase
characters only.

For example: use "VXI0::56::INSTR" instead of "vxi0::56::instr"

2.2 Executing the Soft Front Panel without VISA

The VISA dynamic link library provides a communication library
between your program and the instrument. If you receive a message
that VISA.DLL cannot be found when executing the soft front panel
(hpe1468.exe), VISA is not installed on your system. To communicate
with the Agilent E1468, you must install VISA from discs supplied
with your computer or I/O card. However, it is still possible to
execute the soft front panel in a demonstration mode without VISA
and/or the Agilent E1468. Simply press 'ok' when the dialog box
appears and the soft front panel will then become available.

3. Using the Agilent E1468 Driver in Application Development Environments

This section offers suggestions on using the hpe1468.dll within
various application development environments.

3.1 Microsoft Visual C/C++

Refer to your Microsoft Visual C/C++ manuals for information on linking
and calling .DLLs.

Rebuilding the driver requires header files located in the
~winnthpe1465 or ~win95hpe1465 directory. The ~ refers to the
directory in the VXIPNPPATH variable. By default this is set to
C:VXIPNP on Agilent I/O Libraries revisions prior to J.01.00; or
to C:Program FilesVISA on revisions J.01.00 or later.

3.2 Borland C/C++

Refer to your Borland C/C++ manuals for information on linking and
calling .DLLs.

3.3 Microsoft Visual Basic

Refer to the Microsoft Visual BASIC manual for information on calling DLLs.
The BASIC include file is hpe1465.bas, which is contained in the directory
~winntinclude or ~win95include. The ~ refers to the directory in the
VXIPNPPATH variable. By default this is set to C:VXIPNP on Agilent I/O
Libraries revisions prior to J.01.00; or to C:Program FilesVISA on
revisions J.01.00 or later.

Note that Microsoft Visual BASIC does not support instrument callback
features. Therefore, these functions have been omitted from the
include file.
