I. Main features:
Compact size, full-featured, simple operation, easy to carry. It can be powered by an adapter or a lithium battery. Together with the oscilloscope, it can be used for electronic circuit testing and debugging, testing and measurement of frequency characteristics and impulse response 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, etc.

II. Main technical specifications:
1. Frequency range: sine wave 1Hz-500kHz (where the output amplitude is flat up to 200 kHz, and the output amplitude will be reduced as the frequency is further increased), other waveforms 1Hz-20kHz (but the upper limit of the adjustable frequency is not a limitation, and the use of the frequency can be further increased if the distortion and wobble are not required).
2. Resolution: 1Hz.
3. Output waveforms: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, noise wave, ECG.

Parameters can be saved after setting.
4. Sine wave distortion: <1% below 1kHz, <0.5% above 1kHz.
5. Output amplitude: maximum ±10V (P-P).
6.Output impedance: 50 ohms.
7.DC offset: max ±10V, with shutdown function.

8. There can be open and close the filter, can be well adapted to sinusoidal and pulse waveform output.
8.Power supply: DC3.5-10V, recommend the use of adapter DC5V, battery power supply with 3.7V lithium batteries.
