Description

The SFG-2000/2100 Series Synthesized Function Generator apply Direct Digital Synthesis (DDS), a new technique of frequency synthesis that generates an accurate and stable output frequency with extraordinary resolution. The innovative design of the SFG-2000/2100 Series is exempted from the problems that occurred with the traditional function generators. The main signal source generates waveforms including Sine wave, Square wave and Triangle wave.
