More About this Item

The B&K 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. These instruments generate sine, square, and triangle waveforms with high signal precision and stability and includes gate and burst modes. Unit 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. Unit includes a built-in counter for additional application flexibility.
