Data Sheet DDS Sweep Function Generators Models 4014B and 4040B Features & Benefits ■ 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. 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 Ω (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. ± 4.99 V ) with a small amplitude output signal (e.g. 10 mV), a feature typically found in more expensive generators. These models are suitable for education and other applications that require digital function generators with sweep and modulation capabilities. The 4014B and 4040B are both designed with a dual technology architecture, combining traditional DDS technology with a low-jitter square wave generator.
