The signal generator DIY kit is a product that can generate sine wave, triangular wave, square wave, and positive and negative sawtooth wave. This is a DIY kit requiring soldering and assembly. Using ICL8038 and high-speed operational amplifier, it offers improved accuracy. Capable of outputting sine, triangular, square, and forward/reverse sawtooth waveforms. Frequency range: 5Hz to 400kHz; duty cycle range: 2% to 95% (adjustable). Supports dual power supply operation, no blocking capacitors required, with low signal distortion across high and low frequencies. Frequency and amplitude are adjustable. Frequency adjustment includes coarse and fine tuning functions. All components are through-hole for easy installation. Power supply voltage: 12V to 15V. Low distortion sine wave: 1%. Low temperature drift: 50ppm/°C. Output triangular wave linearity: 0.1%. DC bias range: -7.5V to 7.5V. Output amplitude range: 0.1V to 11VPP (at 12V operating voltage). Board size: 7.8 x 5cm / 3.07 x 1.97 inches. Finished product size: 8.7 x 6 x 1.7cm / 3.43 x 2.36 x 0.67 inches. Material: FR4 + Acrylic. Color: Black. Package Contents: 1 x Low frequency signal generator DIY kit. Only the above package content included; other items not included.
