1 Introduction

1.1 Introduction
The B8000FD series Digital Synthesized Function
generator have the following features:
DDS technology for excellent frequency stability,
frequency resolution and the ability to generate very low
frequencies.
Very precise Sine, Square, triangle, Ramp, Exponential,
Pulse and Sin (X)/X
the key board or encoder dial entry
FSK, ASK, PSK Burst modulation
Low -54dBC Sine wave distortion.
Log and linear sweeps
Internal and External AM and FM modulation.
Dual independent channel outputs;
Built with integrated circuits for high reliability and small
size
Dual back lit LCD display increases the number of
displayed parameters.
Built in 100MHz frequency counter
RS-232 interface, for connecting to a PC.

1.2 DDS Technology

DDS is the abbreviation for Direct Digital Synthesis. It
completely changes the way waveforms are generated.
With the use of High speed digital circuits, memories and
D/A converters a wide range of highly stable, accurate and
complex waveforms may be generated.
waveforms are generated using
