The Instek SFG-2104 is based on Direct Digital Synthesized (DDS) technology and unique FPGA design. The SFG-2104 is 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-2104 has additional functions of Sweep, AM/FM modulation, and External Counter. As a result of the 20ppm stability level and output waveform accuracy, the SFG-2104 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.
