Features: 1. Adjustable Frequency Range – The transmission frequency is no longer fixed at 7.83Hz, but can be adjusted from 0.01Hz to 99999Hz with a precise step value of 0.01Hz, offering greater flexibility and customization than previous models. 2. Multiple Waveform Combination – Supports a variety of waveforms, eliminating confusion over whether the output is a square wave, sine wave, or other waveform types. 3. Full-Color Touch Screen – Equipped with an intuitive smart color touch display that visually corresponds to frequency bands and allows one-touch access to α, β, and γ waves. Simple operation ensures ease of use even for beginners. 4. Convenient Interface & Compatibility – Features a 3.5mm AUX headphone jack for easy connection. Comes with an EU plug suitable for use in Indonesia, Germany, France, Spain, Italy, and other regions (AC 100-240V). 5. Sleek & Durable Design – Made of acrylic with a compact size of 10×80×20cm. The appearance and printed text may vary slightly by batch, but this does not affect performance. Product Details: This advanced wave generator offers precise frequency adjustment from 0.01Hz to 99999Hz, breaking past limitations of fixed-frequency devices. It combines multiple waveforms and is operated via a user-friendly full-color touch screen, which displays real-time frequency bands and allows instant access to α, β, and γ waves with a single touch. Designed for convenience, it includes a 3.5mm AUX output and supports wide voltage input (AC 100-240V) with an EU plug. The compact acrylic housing ensures durability while maintaining a modern look.
