INTRODUCTION

On May 1, 2003, VXI Technology, Inc. acquired Agilent Technology’s mechanical data acquisition product segment. During the transition period, Agilent branded manuals will be provided with the dynamic and static data acquisition products until the manuals have been rebranded. The following products are provided for in this manner.
