Function-(waveform) signal generator. It can generate periodic time-function waveforms (sine wave, square wave, triangle wave, sawtooth wave, and pulse wave, etc.), and the frequency range can be from a few Hz to tens of MHz. The function signal generator has a very wide range of applications in circuit experiments and equipment detection. So learning and designing circuits will also use this. DDS signal generator parameter: Frequency range of 1HZ-65534Hz is: DDS. (no distortion, the enlarged part of TL082) High speed () square wave: 1MHZ/2MHZ/4MHZ/8MHZ signal. The offset amplitude of the DDS signal can be adjusted by two potentiometers. DDS signal: sine wave, square wave, sawtooth wave, inverse wave, triangle wave, ECG wave, and noise wave. 1602 LCD display. Intuitive 5-key keyboard. Step frequency: 1, 10, 100, 1000, 10000Hz. Automatically saves the last setting after power off. Offset: 0.5pp-5Vpp. Amplitude: 0.5Vpp-14Vpp. Output impedance: 20-200 ohm. Power supply: DC 9V.
