4013B - 

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.

Features:

Sine and square waveforms up to 12 MHz

Bright easy-to-read display

Linear and logarithmic sweep

Variable DC offset

Adjustable duty cycle (square)

Store and recall up to 9 instrument settings

Output On/Off button

Overvoltage, overcurrent, and short circuit protection on main output
