Data Sheet DDS Sweep Function Generators Models 4014B and 4040B Features & Benefits Sine and square waveforms up to 12 MHz (4014B) or 20 MHz (4040B) Models 4014B and 4040B are 12 MHz and generate a 2-point waveform to simulate the Triangle/ramp waveforms up to 20 MHz DDS (direct digital synthesis) function amplitude and use a high accuracy PLL generators that generate stable and precise sine, (phase-locked loop) circuit for timing. Compared 1 MHz (4014B) or 2 MHz (4040B) square, and triangle waveforms. Both models to signals generated by typical low-cost DDS Bright color display with waveform preview provide variable output voltages from 0 to function and arbitrary waveform generators, this Linear and logarithmic sweep 10 Vpp into 50 (up to 20 Vpp into open implementation significantly minimizes jitter and AM/FM modulation circuit), linear and logarithmic sweep, AM/FM improves edge stability of square waves. The Independent output and DC offset amplifiers modulation, built-in counter, and a continuously improved signal integrity allows these generators allow for small amplitude output signals with variable DC offset that allows the output to be to be used for simulating reliable clock signals, injected directly into circuits at the correct bias generating triggers, or validating serial data large DC offsets level. Separate output amplitude and DC offset buses. Low-jitter square wave generation amplifiers let you set a large DC offset (e.g. Adjustable duty cycle 4.99 V ) with a small amplitude output signal These models are suitable for education and Output ON/OFF button (e.g. 10 mV), a feature typically found in more other applications that require digital function Internal/external triggering expensive generators. generators with sweep and modulation Gate and burst mode (4040B only) capabilities. The 4014B and 4040B are both designed Built-in counter with a dual technology architecture, combining USB interface traditional DDS technology with a low-jitter SCPI-compliant command set square wave generator.
