Data Sheet

DDS Sweep Function Generators

Models 4014B and 4040B

Models 4014B and 4040B are 12 MHz and

20 MHz DDS (direct digital synthesis) function

generators that generate stable and precise sine,

square, and triangle waveforms. Both models

provide variable output voltages from 0 to

10 Vpp into 50 â¦ (up to 20 Vpp into open

circuit), linear and logarithmic sweep, AM/FM

modulation, built-in counter, and a continuously

variable DC offset that allows the output to be

injected directly into circuits at the correct bias

level. Separate output amplitude and DC offset

amplifiers let you set a large DC offset (e.g.

Â± 4.99 V ) with a small amplitude output signal

(e.g. 10 mV), a feature typically found in more

expensive generators.

The 4014B and 4040B are both designed

with a dual technology architecture, combining

traditional DDS technology with a low-jitter

square wave generator. The instruments

generate a 2-point waveform to simulate the

amplitude and use a high accuracy PLL

(phase-locked loop) circuit for timing. Compared

to signals generated by typical low-cost DDS

function and arbitrary waveform generators, this

implementation significantly minimizes jitter and

improves edge stability of square waves. The

improved signal integrity allows these generators

to be used for simulating reliable clock signals,

generating triggers, or validating serial data

buses.

These models are suitable for education and

other applications that require digital function

generators with sweep and modulation

capabilities.
