FG-200 DDS Function Signal Generator Frequency Counter 0.01Hz - 500KHz Signal Source Module Sine+Square+Sawtooth Waveform

Features:
Compact size, complete functions, simple operation, easy to carry. It can be powered by a power adapter or a 3.7V lithium battery.
Together with an oscilloscope, it can be used for electronic circuit test and debugging, frequency characteristics and impulse response test and measurement of audio amplifiers. Due to the good accuracy and frequency stability of DDS, it is also very suitable for oscilloscope sweep time factor calibration.
The square wave output is suitable for oscilloscope attenuator and probe pulse characteristic adjustment.
Have a filter (can be opened and closed) to suit the output of sine wave and pulse wave.
This functional signal generator can test many kinds of wave forms such as: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, etc. It is especially designed for those professional worker.
