Feature FG-100 DDS Function generator is a low frequency signal generator..
It is small size, full function, easy operating and portable. Its power supply can be either AC/DC adaptor or a Lithium battery..
Working with an oscilloscope, it can be used to troubleshoot the electronic circuit, characterize the audio amplifier frequency response or measure the impulse response..
Due to the excellent DSS accuracy and frequency stability, it can also be used to calibrate the sweep time factor for oscilloscopes. You can also use its square wave to calibrate your oscilloscope attenuator or adjust your oscilloscope probe.
Have a filter (can be opened and closed) to suit the output of sine wave and pulse wave..
