D D S Sw eep Function G enerators M odels 4014B and 4040B D ata Sheet w w w .bkprecision.com Technical data subject to change © B& K Precision Corp. 2013 M odels 4014B and 4040B are 12 M Hz and
20 M Hz D D S (direct digital synthesis) function
generators that generate stable and precise sine, square, and triangle waveform s. B oth m odels provide variable output voltages from 0 to
10 Vpp into 5 0 Ω (up to 20 Vpp into open
circuit), linear and logarithm ic sweep, A M /FM m odulation, built-in counter, and a continuously variable D C offset that allows the output to be injected directly into circuits at the correct bias level. Separate output am plitude and D C offset am plifiers let you set a large D C offset (e.g. ± 4.99 V ) with a sm all am plitude output signal (e.g. 10 m V), a feature typically found in m ore expensive generators. The 4014B and 4040B are both designed with a dual technology architecture, com bining traditional D D S technology with a low-jitter square wave generator. The instrum ents generate a 2-point waveform to sim ulate the am plitude and use a high accuracy PLL (phase-locked loop) circuit for tim ing. C om pared to signals generated by typical low-cost D D S function and arbitrary waveform generators, this im plem entation significantly m inim izes jitter and im proves edge stability of square waves. The im proved signal integrity allows these generators to be used for sim ulating reliable clock signals, generating triggers, or validating serial data buses. These m odels are suitable for education and other applications that require digital function generators with sweep and m odulation capabilities.
