5MHz DDS (Direct Digital Synthesis) Function Generator

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.

• 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
• Adjustable duty cycle and DC offset
