E1420A/B High Performance Universal Counter Instrument Driver

This VXIplug&play driver is designed for computers operating either Windows® 95 or Windows® NT Version 3.51 or higher. The driver requires a VISA-compatible GP-IB/GPIB interface and the VISA® I/O Library Version 1.1 or higher. Programming with this driver does not depend upon an I/O library specific to your brand of GP-IB/GPIB interface, thus your programming code becomes much more portable. Visual Basic® and Visual C++/Borland C++® Programming Examples using this driver, if available, are built-in to the Windows Help file for the driver.

The attached file is a executable installation file. Download the file to an empty directory on the hard drive of your computer and run the program to begin the installation. A help file is included with the installation that can answer questions you might have about the driver. Please note that this driver may have originally been developed under the Hewlett-Packard name.
