Output Characteristics

The B&K Precision model 4005DDS is a versatile 5 MHz DDS (direct digital
synthesis) function generator with a 4-digit display. The instrument generates
sinusoidal, triangular, and square waveforms over the 1 Hz to 5 MHz range.
The output voltage can be varied from 0 to 10 Vp-p into 50 ohms or to 20
Vp-p into open circuit. A continuously variable DC offset allows the output to
be injected directly into circuits at the correct bias level. These features make
the 4005DDS great for education and other applications that need basic
waveform generation.

Features and Benefits

■ Frequency is selectable from 1 Hz to 5 MHz

■ Sine, square, or triangle waveform output

■ Direct digital synthesis (DDS) architecture

■ Bright, easy-to-read LED display

■ Number pad for quick input of frequency

■ Front panel push button and pull knob can attenuate output

by up to 40 dB

Kensington security slot helps secure your function
generator and prevents theft.
