Precise Signals Frequency Generator USB Powered For Scientific Experiments And Relaxation Therapy Circuit Debugging Multicolor

Features: This 7.83Hz tunable signals generator features digital crystal oscillator technology with adjustable frequency from 0.1Hz to 30KHz, ideal for laboratory precise testing and biological frequency research applications. The black model supports sine/square/inverted square waving outputs, catering to diverse needs like electronic circuit debugging, unlike the green version's single sine waving. Equipped with USB and DC5.5 double power supply option, for power banks or car adapters, perfect for field exploration or mobile medical teams requiring outdoor power solution. Default 7.83Hz frequency with 0.01-100000Hz tuning ranging creates resonance to alleviate anxieties, for meditation rooms and psychological counseling environments. Optimized circuit design ensures quiet, heat less performances with reliably continuous operations, making it perfect for prolonged health management and experimental research.
