Stable output frequency, low distortion, and fine frequency resolution DDS technique and FPGA chip design Front panel setting save or recall with 10 groups of setting memories 100 MHz frequency resolution Measures 266mm width by 107mm height by 293mm depth Based on the direct digital synthesized (DDS) technology and unique FPGA design, the SFG-2000 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. As a result of the 20ppm stability level and output waveform accuracy, The SFG-2000 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, 100 MHz Bandwidth for electronic devices. 1 User manual, 1 Power cord and 1 GTL-101.
