The BK Precision 4040B DDS Sweep Function Generator is a Direct Digital Synthesis (DDS) function generator which generates stable and precise sine, square, and triangle waveforms. This unit provides variable output voltages from 0 to 10 peak-to-peak voltage into 50 ohms, 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 allow the user to set a large DC offset with a small amplitude output signal. The BK Precision 4040B DDS Sweep Function Generator is designed with a dual technology architecture, combining traditional DDS technology with a low-jitter square wave generator. The unit generates a 2-point waveform to simulate the amplitude and utilize a high accuracy Phase-Locked Loop (PLL) circuit for timing. This implementation significantly minimizes jitter and improves edge stability of square waves. The improved signal integrity allows this unit to be used for simulating reliable clock signals, generating triggers, validating serial data buses. The BK Precision 4040B DDS Sweep Function Generator is well suited for education and other applications which require digital function generators with sweep and modulation capabilities.

Intuitive User Interface
The BK Precision 4040B DDS Sweep Function Generator allows the user to easily change all waveform parameters using the intuitive menu-driven front panel keyboard, rotary control knob, and large color LCD screen which shows a preview of the output waveform. The convenient waveform and range selection buttons allow the user to make quick and precise adjustments to the output signal.

Versatile Tools
The BK Precision 4040B DDS Sweep Function Generator provides AM and FM modulation along with linear and logarithmic sweep and built-in counter capabilities. Internal and external sources can be used for triggering and modulating the signal.

Easy PC Connectivity
The BK Precision 4040B DDS Sweep Function Generator can be programmed remotely via the USB (virtual COM) interface using SCPI commands. Application software for the unit is also available to download which provides virtual front panel emulation. This emulation allows users to remotely control the unit without the need for programming.
