1. Introduction

The help file included with the Agilent AGE8480A VXIplug&play driver contains
instrument and programming information. This readme file contains
additional information for the Agilent VXIplug&play programmer.

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

2. VTL/VISA Specific Information

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

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 VTL/VISA

The VTL/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
(AGE8480A.exe), VTL/VISA is not installed on your system. To
communicate with the Agilent AGE8480A, you must install VTL/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 VTL/VISA and/or the Agilent AGE8480A. Simply press 'ok' when the
dialog box appears and the soft front panel will then become
available.

3. Using the Agilent AGE8480A Driver in Application Development Environments

This section offers suggestions on using the AGE8480A.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.

A.) The driver uses stdcall calling conventions.

B.) In addition to the AGE8480A.h header file located in the
the ~vxipnpwin95include directory, the driver needs additional
header files located in the ~vxipnpwin95AGE8480A directory. The
~ refers to the directory in the VXIPNP variable. By default this
is set to C:.

3.2 Borland C/C++

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

A.) The driver uses stdcall calling conventions.

3.3 Microsoft Visual Basic

Refer to the Microsoft Visual BASIC manual for information on calling DLLs.
The BASIC include file is AGE8480A.bas, which is contained in the directory
~vxipnpwin95include. The ~ refers to the directory in the VXIPNP variable. 
By default this is set to C:.

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