Schumann Wave Generator Pure Sine Signal Generator 0.1–100kHz

Etmakit Schumann Wave Generator – Pure Sine Frequency Modulation Signal Generator

Explore the fascinating world of ultra-low frequency waves with the Etmakit Schumann Wave Generator. This CE-certified, professionally engineered signal generator produces pure sine waves across an ultra-wide frequency range of 0.1 Hz to 100,000 Hz, with a default output set to the naturally occurring Earth resonance frequency of 7.83 Hz. Whether you're a hobbyist, audio enthusiast, researcher, or simply curious about Earth's natural electromagnetic resonance, this compact device is designed to impress.

Housed in a clear, high-transparency acrylic shell, the device features a highly integrated digital circuit board that replaces traditional analog components — delivering superior stability, minimal interference, and consistent waveform accuracy. Simple button controls mean anyone can operate it right out of the box.

Made in Mainland China.
