VXIplug&play Power Products Instrument Drivers

VXIplug&play instrument drivers for Microsoft Windows 95 and Windows NT are now available on

the Web at http://www.agilent.com/find/drivers. These instrument drivers provide a high-level

programming interface to your Agilent Technologies instrument. VXIplug&play instrument drivers are

an alternative to programming your instrument with SCPI command strings. Because the instrument

driver's function calls work together on top of the VISA I/O library, a single instrument driver can be

used with multiple application environments.

Supported Applications

( Agilent VEE

( Microsoft Visual BASIC

( Microsoft Visual C/C++

( Borland C/C++

( National Instruments LabVIEW

( National Instruments LabWindows/CVI

System Requirements

The VXIplug&play Power Products instrument driver complies with the following:

( Microsoft Windows 95

( Microsoft Windows NT 4.0

( HP VISA revision F.01.02

( National Instruments VISA 1.1

Downloading and Installing the Driver

NOTE: Before installing the VXIplug&play instrument driver, make sure that you have one of

the supported applications installed and running on your computer.

1. Access Agilent Technologies' Web site at http://www.agilent.com/find/drivers.

2. Select the instrument for which you need the driver.

3. Click on the driver, either Windows 95 or Windows NT, and download the executable file to your pc.

4. Locate the file that you downloaded from the Web. From the Start menu select Run

<path>:\agxxxx.exe - where <path> is the directory path where the file is located, and agxxxx is the

instrument driver that you downloaded .

5. Follow the directions on the screen to install the software. The default installation selections will

work in most cases. The readme.txt file contains product updates or corrections that are not

documented in the on-line help. If you decide to install this file, use any text editor to open and read

it.

6. To use the VXIplug&play instrument driver, follow the directions in the VXIplug&play online help

under “Introduction to Programming”.
