Adjustable Schumann Wave Generator, Pure Sine Wave Signal Generator with Antenna Board,Frequency Signal Source Module

Adjustable Schumann Wave Generator, Pure Sine Wave Signal Generator with Antenna Board,Frequency Signal Source Module Kuvaus

The frequency is continuously adjustable, ranging from a minimum of 0.1 Hz to a maximum of 99,999 Hz with precise stepping. It covers the spectrum from ultra-low to high frequencies, making it suitable for applications ranging from biological frequency research and audio testing to industrial control.
The main unit features a dual-channel audio interface (headphone jack) that supports the connection of a dedicated external antenna board (10x10 cm) via an AUX cable to extend the signal radiation range. It also supports daisy-chaining multiple units; by connecting the headphone jacks of the devices in sequence using AUX cables.
Upon startup, the default frequency is set to 7.83 Hz (Schumann resonance).You can override this setting by either long-pressing the controls or directly entering a new value and pressing the confirmation key.Returning to the default frequency requires just a single press-no complex menus involved-making it easy for beginners to get started quickly
The device features a dedicated numeric keypad and a confirmation key (OK), eliminating the need for computer software or mobile apps. For instance, to set the frequency to 888 Hz, simply press [8], [8], and [8] after powering , then press [OK]; the entire process takes only two seconds.
A single main unit can drive to 10 external antenna boards simultaneously via daisy-chaining, making it ideal for scenarios requiring wide-area signal coverage or synchronized multi-point output, such as in exhibition halls, laboratories, or classrooms.
