INTRODUCTION

1.1

The Amplicon 200 Series

The 

Amplicon  200 Series

 of Personal Computer based data acquisition products provides very 

high performance, affordable hardware with user sympathetic software. The 200 Series is 
designed for users requiring fast or complex data input/output to the host PC and comprises a 
range of boards and software to handle most analog and digital signal types.

When a large scale system is required, multiple boards can be added from the 200 Series without 
conflict.
