Unstable Frequency Output No Longer Limits Your Work
Generate programmable pure sine waves from 0.01 Hz to 100 kHz — 3 V output, real-time 2.9-inch display, Type-C powered without a dedicated supply.
Why Is This Frequency Generator Perfect for You?
✔ Stable, clean frequency output: Low-temperature-drift crystal oscillators and a high-precision DAC help maintain stable frequencies and pure sine waves across the programmable range. Digital crystal oscillator referencing helps resist interference from nearby electronics.
✔ Programmable from 0.01 Hz to 100 kHz: Adjust frequency continuously from ultra-low frequencies to audio resonance applications. A preset 7.83 Hz Schumann resonance and a 2.9-inch display showing settings in real time make frequency selection straightforward.
✔ Portable Type-C power: Use common USB power sources, including power banks, laptops, and adapters, without requiring a dedicated power supply. The compact acrylic-shell design measures 6.10 × 4.13 × 1.02 inches for desktop or field use.

Many orders are processed sooner, but during busy periods such as promotions, holidays, or peak seasons, additional processing time may be required.

Once your order has been processed, shipping typically takes 3–10 business days.
