FG-100 1Hz-500kHz DDS Function Signal Generator Frequency Counter 1. Small size, complete functions, simple operation and easy to carry. 2. It can be powered by an adapter or a lithium battery (not included) 3. Together with an oscilloscope, it can be used for testing and debugging electronic circuits, testing and measuring the frequency characteristics and impulse response of audio amplifiers. Due to its good accuracy and frequency stability, DDS is also very suitable for oscilloscope scan time factor calibration. Square wave output is suitable for oscilloscope attenuator and probe pulse characteristic adjustment, etc. Technical indicators: 1. Frequency range: sine wave 1Hz-500kHz (the frequency with flat output amplitude reaches 200 kHz, and the output amplitude will decrease as the frequency further increases), other waveforms 1Hz-20kHz (but the upper limit of the adjustable frequency is not limited, if The requirements for distortion and shaking are not high, and the frequency of use can be further increased). 2. Resolution: 1Hz. 3. Output waveform: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, noise wave, electrocardiogram. 4. Sine wave distortion: less than 1% below 1kHz, less than 0.5% at 1kHz and above. 5. Output amplitude: maximum +-10V (P-P). 6. Output impedance: 50 ohms 7.. DC offset: maximum +-10V, with shutdown function. 8. There is a filter that can be turned on and off, which can be well adapted to sine and pulse waveform output. 9. Power supply: DC3.5-10V. It is recommended to use DC5V when using an adapter and 3.7V lithium battery when using battery power. 10. Overall dimensions: 125x80x32. 11. Weight (including accessories): about 0.2kg
