The BK Precision 4040B is a versatile sweep function generator, designed with a dual technology architecture combining direct digital synthesis (DDS) and a low-jitter square wave generator. This instrument generates sine, square, and triangle waveforms with high signal precision and stability.

This sweep function generator provides variable output voltages from 0 to 10 Vpp into 50 ohms (up to 20 Vpp into open circuit), linear and logarithmic sweep, AM/FM modulation, and a continuously variable DC offset to inject signals directly into circuits at the correct bias level.
