Ultra-Low Frequency Sine Wave Signal Generator with 7.83 Hz Earth Resonance Setting & 0.01–100,000 Hz Range

Precision Signal Generation From Deep Infrasonic to Audio Range

You need accurate, stable sine wave output for your frequency research, meditation setup, or signal testing. This compact laboratory-grade signal generator delivers pure analog waveforms across an extraordinary 0.01 Hz to 100,000 Hz spectrum, powered by temperature-stabilized crystal oscillator technology and a dedicated high-resolution DAC chip that maintains clean output at any frequency you select. Whether you're exploring Earth resonance frequencies, designing audio experiments, or building custom electronics projects, you get precise control with a direct numeric keypad, real-time LCD readout, and both audio output and oscilloscope test connections. Powers via any USB-C phone charger and runs continuously on just 12 milliamps—reliable frequency generation for desktop, lab bench, or portable field use.

Why You Need This

• Crystal-Stabilized Accuracy: Temperature-compensated oscillator and precision DAC deliver undistorted sine waves with minimal drift across the entire adjustment range.
• Massive 0.01–100,000 Hz Span: Generate frequencies from ultra-slow infrasonic pulses through the complete audible spectrum using direct numeric entry on the built-in keypad.
• Instant 7.83 Hz Earth Resonance Default: Powers on automatically to the fundamental planetary resonance frequency—press the restore button anytime to return from any custom setting.
• Dual Output Interface: Standard 3.5 mm audio jack connects to amplifiers and speakers; dedicated oscilloscope test point lets you verify waveform quality with probe gear.
• Clear LCD Display & Simple Controls: Backlit screen shows your selected frequency in real time; four-button interface makes frequency entry and adjustment straightforward from the first use.
• Spiral Antenna & Compact Enclosure: Dual-sided low-frequency transmission coil in a transparent protective case measuring 6.1 × 4.1 × 1 inch—desk-friendly and easy to integrate.

Built for Exploration and Experimentation

This signal generator is designed for anyone who values precision, versatility, and ease of use in frequency work. The crystal oscillator core resists environmental interference, the numeric keypad accepts exact frequency values (no guessing with dials), and the 3-volt peak-to-peak output is ready to drive signal amplifiers, audio equipment, or measurement instruments. Use it as a standalone frequency source on your workbench, connect it to powered speakers for acoustic output, or verify waveform purity with an oscilloscope probe. With working current under 15 milliamps, you can run it all day from a laptop USB port or portable power bank. Ships with protective acrylic housing, USB-C power interface, and an output indicator LED. Enjoy free shipping across the United States and a 30-day return window—start exploring low-frequency signal generation with confidence.
