Custom Frequency Generator V2 (with acrylic shell) Overview A compact, userprogrammable frequency generator designed for imprinting frequencies onto objects and for audio output. The unit produces a clean pure sine wave and offers fine frequency control across a wide range. It connects via USBC for power and provides a 3.5 mm audio output for headphones or speakers. Key benefits Precise frequency control: Adjustable from 0.01 Hz to 30000 Hz with a default setting of 7.83 Hz, allowing exact selection for varied applications. Clean output: Pure sine wave output with a signal amplitude of 3 V for stable, lownoise performance. Flexible power and audio options: USBC power input and 3.5 mm audio output enable use with wall adapters, laptops, power banks, headphones, and external speakers. Portable and durable: Acrylic shell protects internal components while keeping the unit lightweight and transportable. What makes it stand out Wide adjustment range and fine resolution for detailed frequency work. Accurate sine wave output and defined signal amplitude for predictable results. Simple touch pad entry and straightforward operation for quick setup. Includes a USB cable optimized for improved conversion rates. How to use Connect the provided USBC cable to the device and plug it into a wall adapter, laptop, or power bank. Plug headphones into the 3.5 mm output or connect an external speaker using an AUX cable. Enter the desired frequency using the touch pad on the device. Press the Ok button to start output at the selected frequency.
