DDS Sweep Function Generators from B&K Precision.
The BK4007B and BK4013B are versatile DDS (direct digital synthesis) sweep function generators with high signal precision and stability. These instruments generate sine and square waveforms up to 7 MHz or 12 MHz, including triangle waveforms up to 1 MHz. Both models provide variable output voltages from 0 to 10 Vpp into 50 ohms or up to 20 Vpp into open circuit. A continuously variable DC offset allows the output to be injected directly into circuits at the correct bias level.
Easily change all waveform parameters using the intuitive menu-driven front panel keypad, control knob, and easy-to-read LCD. Convenient waveform and range selection buttons let users make quick and precise adjustments.
