Compact size, full-featured, simple operation, easy to carry.<br> 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.<br> Due to the good accuracy and frequency stability of DDS, it is also very suitable for oscilloscope sweep time factor calibration.<br> The square wave output is suitable for oscilloscope attenuator and probe pulse characteristic adjustment, etc.<br> Main technical specifications:<br> 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).<br> 2. Resolution: 1Hz.<br> 3. Output waveforms: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, noise wave, ECG. Parameters can be saved after setting.<br> 4. Sine wave distortion: Less than 1% below 1kHz, Less than 0.5% above 1kHz.<br> 5. Output amplitude: maximum ±10V (P-P).<br> 6. Output impedance: 50 ohms.<br> 7. DC offset: max ±10V, with shutdown function.<br> 8. There can be open and close the filter, can be well adapted to sinusoidal and pulse waveform output.<br> 9. Power supply: DC3.5-10V, recommend the use of adapter DC5V.<br> Colour:White<br> Material:Plastic<br> Package Contents:<br> 1 * Function Signal Generato<br> 1 * USB cable<br> 1 * BNC cable<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
