Frequently Asked Questions

Q: What is the default frequency of this Schumann Wave Generator?

A: The device defaults to 7.83Hz — Earth's natural Schumann resonance frequency — every time it powers on. You can manually adjust the output to any frequency between 0.1Hz and 30,000Hz using the built-in keypad and LCD display.

Q: What power source does this signal generator require?

A: The generator runs on 5V via Micro USB or a DC 5.5×2.1mm connector. It is compatible with standard USB power banks, USB wall adapters, and laptop USB ports, making it highly portable and versatile for home, lab, or travel use.

Q: What is the difference between the green and black model options?

A: The green model outputs a pure sine wave only, ideal for straightforward Schumann resonance and wellness applications. The black model adds expanded waveform options including sine, square, and inverted square waves, making it better suited for broader signal generation and lab testing needs.

Q: Can this device be used for lab testing and DIY electronics projects?

A: Yes. With its crystal oscillator frequency reference, wide 0.1Hz–30KHz tunable range, and stable digital output, this adjustable signal generator is well-suited for lab testing, electronics experimentation, DIY projects, and frequency research applications.
