Based on Direct Digital Synthesized (DDS) technology and unique FPGA design, SFG-2000/2100 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.
SFG-2000/2100 Series include four members in each family at 4MHz, 7MHz, 10MHz and 20MHz
bandwidth, respectively. SFG-2100 Series has additional functions of Sweep, AM/FM modulation, and
External Counter. As a result of the 20ppm stability level and output waveform accuracy, SFG-2000/
2100 Series well fits 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.
