FG300 0.001Hz–200kHz 1.8-inch TFT colour screen Schumann wave generator Sine wave triangle wave square wave USB Type-C 5V

Product Features:1. Utilises low-temperature drift crystal oscillators with high-precision DDS frequency synthesis, delivering exceptional frequency stability with resolution down to 0.001Hz. At low frequencies, accuracy reaches 0.001Hz.2. Supports 13 waveform outputs to accommodate diverse requirements.3. Features a colour 1.8-inch TFT LCD display with direct frequency input via numeric keypad for intuitive operation.4. Features automatic shutdown timer, adjustable signal indicator brightness, and adjustable display backlight brightness.5. All configuration parameters are automatically saved; no need to reset upon subsequent startup.Product Overview:The FG-300 is a multifunctional, high-precision, portable signal generator capable of producing sine waves, square waves, triangular waves, forward sawtooth waves, reverse sawtooth waves, electrocardiogram (ECG) waveforms, half-wave, Lorentzian, Gaussian, Sinusoidal, exponential rise, exponential fall, and 7.83Hz Schumann waves. The integrated helical antenna functions as a high-precision Schumann wave generator, suitable for electronic R&D, production testing, education, maintenance, and audio testing.Product Specifications:Frequency Range:Sine wave: 0.001Hz–200kHz (output amplitude remains flat up to 100kHz; beyond this, amplitude decreases and distortion increases with frequency).Other waveforms: 0.001Hz–20kHz (though the adjustable upper frequency limit is unrestricted; usage frequency may be further increased if distortion and fluctuation tolerances are not stringent).Waveform Types: Sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, electrocardiogram (ECG), half-sine wave, Lorentzian wave, Gaussian wave, Sinusoidal wave, exponential rise, exponential fall, and 7.83Hz Schumann waveOutput Amplitude: 2.5V VPPOutput Impedance: 330ΩDisplay: 1.8-inch TFT screenPower supply voltage: USB Type-C 5VDimensions: 127 × 98 × 18 mmPackage contents:Main unit ×1Type-C power cable ×14-pin signal output cable ×1Stylus pen ×1
