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 at precise frequencies. 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.
