DDS Function Signal Generator Module 0.01Hz-500KHz Frequency Counter Sine and Square Wave Source

I. Main Technical Parameters: 1. Output Waveforms: Sine wave, square wave, triangle wave, sawtooth wave (rising and falling), ECG wave, exponential rise, exponential fall, Lorentz pulse, Gaussian pulse, Sinc pulse, half-wave, full-wave, Schumann wave, noise wave — 15 waveform types. 2. Power Supply: DC 4–9 V; DC 5 V recommended when using an adapter; 3.7 V lithium battery recommended for battery operation. 3. Current Consumption: 180 mA at 5 V. 4. Frequency Range: - Sine wave: 0.01 Hz – 500.00 kHz (output amplitude decreases beyond this range); - Other waveforms: 0.01 Hz – 100.00 kHz (frequency can be extended further if distortion and jitter requirements are relaxed). 5. Frequency Resolution: 0.01 Hz. 6. Sine Wave Total Harmonic Distortion: <1% below 1 kHz; <0.5% above 1 kHz. 7. Output Amplitude: Up to 10 V peak-to-peak (Vpp). 8. Output Impedance: 50 Ω. 9. DC Offset: Up to ±10 V, with shutdown function. 10. All settings can be saved. 11. Built-in filters can be enabled or disabled to optimize sine and pulse waveform output. II. Features: Compact size (125 × 80 × 26.5 mm), fully functional, intuitive operation, portable design. Powered by either a DC adapter or a 3.7 V lithium battery. When used with an oscilloscope, suitable for electronic circuit testing and debugging, frequency response analysis, impulse response measurement, and audio amplifier testing. High accuracy and frequency stability make it ideal for oscilloscope timebase calibration. Square wave output supports oscilloscope attenuator and probe pulse response adjustment. Note: Minor variations may occur between production batches. Color: As shown in image Material: Plastic Package Contents: 1 × Function Generator
