Product Description

Features:
The Schumann Resonance Generator outputs a pure sine wave that cultivates a calm, soothing environment, helping you release stress and restore mind-body balance. On birthdays, Christmas or any special occasion, it makes a heart-warming gift for family and friends. The included acrylic dust cover keeps the circuit board safe from dust and accidental knocks.
Defaults to a stable 7.83 Hz output and offers dual voltage amplitudes: 3V sine wave or 5V square wave. A digital-circuit crystal oscillator provides an ultra-stable frequency reference, delivering superior frequency stability and stronger immunity to interference.
Besides the 7.83 Hz Schumann resonance, the frequency machine features programmable frequency modulation that can be tuned anywhere from 0.01 Hz to 200 kHz. Instantly dial in popular frequencies such as 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, 963 Hz, and more—perfectly matching different scenarios and personal needs.
A compact PCB keeps this frequency healing device light and travel-ready. USB-powered, it plugs in anywhere at home or on the road. Enter any frequency directly on the numeric keypad; the clear interface lets you customize auto-off timers, indicator brightness and backlight levels. All settings are saved automatically, so it's ready to go the moment you power it on.
The frequency device delivers sine, square, inverted square, positive & negative sawtooth, ECG, half-wave and eight additional waveforms 13 in total. Whether for scientific exploration or everyday wellness, one device meets a universe of needs.

Specifications:
AntennaWaveform: Sinewave
Interface waveform: Sinewave, squarewave, inverted squarewave
Power supply: 5V, USB-C powered (no battery; must remain USB-C cable connected).
Signal voltage amplitude: 3V
Rated power consumption: <1W
Default frequency: 7.83Hz
Adjustment range: 0.001Hz-200KHz
SineSignal voltage amplitude: 3V
SquareWave signal voltage amplitude: 5V

Pin cable purpose:
Provides the oscilloscope with direct access to the generator's Schumann-wave signal for waveform verification.
How to use:
Plug the 4-pin connector into the unit's SIGNAL OUTPUT port, then clip the color-coded alligator leads to the scope's probe tips (GND to ground, SIG to the input).

Notes:
Screen-off (power-save): After 2 minutes of inactivity, the screen turns off, but the frequency continues to run.
Screen-on: Tap the power key once to wake the screen; the FREQ (Hz) display shows the current value and the red ''='' icon indicates active output.
Power-up check: If the unit were off, a single press would do nothing; a 3-second long-press is required to start it from shutdown.

Package Includes:
‎1PCS Schumann wave generator
1PCS USB cable
1PCS Touch pen
1PCS Pin cable
