Mini DDS Function Generator

This is a low cost yet versatile function generator capable of producing many different waveforms. As an easy-to-use tool operation of FG085 is very simple and straightforward. It is an ideal test/experiment tool for electronics hobbyists and students. Specification Frequency range: 0 - 200KHz (Sine) Frequency resolution: 1Hz Period resolution: 1ms Amplitude range: 0 - 10V peak-to-peak Offset range: -5V - +5V Memory depth: 256 bytes Sample rate: 2.5Msps Output impedance: 50 ohm Power supply voltage: DC 15V Current consumption: < 150mA (without loading) Dimension: 155 X 55 X 30 mm Net weight: 100 gram Features implemented as of current firmware Generating continuous Sine, Square, Triangle, Ramp (up and down), and Staircase (up and down) signals Generating servo test/control signals with user defined pulse width, amplitude, and cycle [ NEW ] Setting of frequency (or period), amplitude, and offset is done with digits - quick and straightforward Frequency (period), amplitude, and offset can be incrementally adjusted up and down with rotary encoder Settings are memorized after power down. Can be used as an adjustable DC voltage source by setting amplitude to 0 Features to be implemented (hardware support already in place) Generating arbitrary signals Generating special test signals NTSC/PAL video synchronous signal, and more Generating sweeping signal with continuous phase USB connection for waveform download and control Programmable frequency, amplitude, and offset Synchrous output Burst output at trig Manual and Resources can be downloaded here.
