Features:
Output Waveform -- Sine, wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, electrocardiogram wave(ECG wave), noise wave, high-speed square wave.
DDS Frequency Range -- Sine wave 1- 500KHz (the output amplitude will decrease with the further increase of frequency), other waveforms 1 Hz-100KHz (but the upper limit of adjustable frequency is not limited, if the distortion and shaking requirements are not high, use the frequency can be further increased).
Application -- Due to the excellent DSS accuracy and frequency stability,it can be used in learning and design circuit. You can also use its square wave to calibrate your oscilloscope attenuator or adjust your oscilloscope probe.
Versatile Power Supplu -- Its power supply can be either DC adaptor or a Lithium battery. Power supply range DC 4-10V, it is recommended to choose DC 5V when using the adapter, and 3.7V lithium battery when using battery power.
Large LCD Screen -- Large LCD display with backlight for easy instant reading. 5 function button for easy operation, offset and amplitude knobe for high precision control.
