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