Precision DIY signal generator kit for electronics testing and prototyping Key benefits - Wide frequency range for versatile testing: 5 Hz to 400 kHz with a duty cycle adjustable from 2% to 95% - Flexible waveform output: sine, Triple-Cornered, square, and forward and reverse sawtooth waves - High accuracy design: powered by ICL8038 and a high-speed operational amplifier for improved waveform fidelity - Clean output with flexible drive: supports bi-amping, no block capacitors, and adjustable frequency and amplitude to minimize distortion across bands - DIY kit for hands-on building: a professional product to solder and install, suitable for learning and custom setups What it is - A professional signal generator DIY kit that can generate sine wave, Triple-Cornered wave, square wave, and positive/negative sawtooth waves. This is a solder-and-install kit. Use scenarios - Bench testing: provide a reliable source for oscilloscopes, amplifiers, filters, and other signal-path components during calibration and debugging - Development and prototyping: evaluate op-amps, DACs/ADCs, filters, and audio or RF circuits across a wide frequency range - Education and demonstrations: hands-on learning about waveform generation, timing, and distortion control in electronics labs
