Key benefits Versatile signal generator for electronics projects, testing, and education. Produce sine, triangle, and square waves with reliable output to validate circuits and experiment with signals. Wide frequency range and adjustable amplitude enable a broad set of applications, from microcontroller debugging to RF and audio circuit work. Five levels of frequency resolution with coarse and fine adjustments give precise control over the output for accurate measurements and repeatable results. Flexible power options: use an external 912 V DC supply or a 9 V battery for bench testing, field work, or portable use. DIY kit with a protective shell provides a compact, readytouse package after assembly, combining ease of use with handson electronics practice. What you get and how it helps Waveform options: sine, triangle, and square waves to suit different testing needs and circuit characteristics. Adjustable settings: frequency from 1 Hz to 1 MHz and variable amplitude to match your test requirements and signal levels. Precision control: fivestep frequency resolution with both coarse and fine tone adjustments for accurate signal tuning. Power flexibility: supports external 912 V DC supply or a 9 V battery, enabling flexible lab or field operation. Ready for deployment: assembled in a protective shell as a DIY kit, enabling quick setup and portability after assembly. Use scenarios Microcontroller and digital circuits: generate clean test signals to validate PWM, timing, and signal integrity, and observe responses with an oscilloscope or logic analyzer. Audio and RF projects: test filters, amplifiers, and small RF circuits by applying stable sine, triangle, or square waves across the required frequency range. Educational and hobbyist experiments: learn waveform concepts, frequency response, and signal generation techniques through handson building and testing.
