Models 4007B and 4013B 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. These models are suitable for education and other applications that need basic DDS function generators with sweep capability.

Intuitive user interface:
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.
