Schumann Frequency Generator 7.83Hz – Low-Frequency Sine Signal with LCD Display for Research 0.01-100kHz | Sansoti

Discover Stable Low-Frequency Sine Waves with a Crystal Oscillator

This compact frequency generator delivers precise analog sine signals from 0.01Hz to 100,000Hz, with crystal oscillators that remain temperature-stable and a high-quality DAC chip that produces clean waveforms. The device automatically starts at the natural 7.83Hz Earth resonance, but you can fully adjust the output using the numeric keypad. The LCD screen continuously displays the active frequency, while the dual spiral antenna effectively distributes the signal. Ideal for relaxation sessions, meditation practices, and electronic experiments where stable low-frequency signals are essential.

Why This Frequency Generator Is Perfect for Your Setup

• Extremely wide frequency range: adjust from an ultra-low 0.01Hz to 100,000Hz in the audio spectrum, with the same clean sine wave across the entire range
• Direct numeric input: enter any desired frequency using the number keys and confirm with OK, without complicated menus or rotary dials
• Crystal-stable reference: low-temperature-drift oscillators and a digital crystal reference provide consistent output that withstands external interference
• 3.5mm audio output: connect directly to signal amplifiers, audio systems, and speakers for amplified acoustic output of the generated signal
• Oscilloscope interface: verify the output signal directly using standard oscilloscope probes, with a 3V signal amplitude visible on the display
• Energy-efficient operation: consumes just 9-14mA via Type-C USB, perfect for continuous use with any phone charger or computer USB port

Designed for Precision and Versatile Applications

Whether you use the natural 7.83Hz Earth resonance to create a calming atmosphere in your space, investigate specific frequencies for sound experiments, or build test setups where stable low-frequency signals are essential - this generator provides the flexibility and accuracy you need. The dual spiral antenna with a double-sided design effectively distributes the signal throughout the space, while the audio output enables direct connection to external equipment. The compact transparent acrylic housing protects the electronics and fits on any desk, bedside table, or workbench. With the RES reset button, you can return to the standard 7.83Hz setting at any time without reprogramming. You can switch the LCD screen backlight on as desired for optimal readability in all lighting conditions.
