3MHz DDS function generator

High resolution using DDS technology High frequency accuracy : 20ppm the ideal equipment of electronic engineers, laboratorie

DDS function generator AT1645(3MHz)

INTRODUCTION

This series uses the latest Direct Digital synthesis (DDS) technology to generate stable, high resolution output frequency. The DDS technology solves several problems encountered in traditional function generators like the Temperature change inside the generator greatly affects the components characteristics which lead to output frequency change. The results are poor accuracy and stability etc.AT1645 is the ideal equipment of electronic engineers, laboratories, production lines and the teaching and research labs.
