Based on the Direct Digital Synthesized (DDS) technology and unique FPGA design, the SFG-2000 and SFG-2100 Series Function Generators are built with exceptionally high performance far exceeding that of any conventional function generators at a very competitive price. Stable output frequency, low distortion, and fine frequency resolution are the most remarkable characteristics of this product series.
The SFG-2000 and SFG-2100 Series include four members in each family at 4MHz, 7MHz, 10MHz and 20MHz bandwidth. As a result of the 20ppm stability level and output waveform accuracy, the SFG-2000 and SFG-2100 Series fit into a wide variety of applications, such as signal generator for experiment labs, reference signal for PLL (Phase Locked Loop), and calibration and adjustment source for electronic devices.
The SFG-2000 and SFG-2100 Series provide Sine, Triangle and Square waveforms with DC offset and variable duty cycle at 20ppm frequency stability and accuracy. The low drift rate and -55dBc low sine wave distortion output significantly extend product application ranges in various market sectors.
The TTL/CMOS output is also available to fulfill various requirements. In addition to the basic functions, the SFG-2100 Series provides advanced functions such as AM/FM modulation, sweep mode, and a built-in frequency counter.
The SFG-2000 and SFG-2100 Series generate signals by continuously delivering a series of sampling values from a sine waveform table (stored in RAM) to a DAC (Digital to Analog Converter) for waveform construction. With a low pass filter circuit to filter out the harmonics of the DAC output and smooth the signal, the SFG-2000 and SFG-2100 Series are able to provide a stable output with very low waveform distortion.
