Key benefits Versatile waveform generator with a library of 15 waveform types to cover a wide range of testing, development, and educational needs. Flexible power options for portable and bench use: can be powered from DC 4 to 9 V, with a 5 V adapter recommended for performance or a 3.7 V lithium battery for battery operation. Clear, reliable specifications for consistent signal generation at typical lab reference levels. Technical specifications Output waveforms: 15 kinds including sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, ECG wave, exponential rise, exponential fall, Lorentz pulse, Gauss pulse, Sinc pulse, halfwave, wave, wave, noise wave, and so on 15 kinds of waveforms. Current: 180 mA at 5 V. Power supply: DC 4–9 V. Power options: DC 5 V is recommended when using an adapter; 3.7 V lithium battery is recommended when using battery power. Recommended power configurations If using an external adapter: provide DC 5 V for performance. If using a battery: use a 3.7 V lithium battery. Use scenarios Electronics development and testing: generate reference signals for microcontrollers, ADCs, or data acquisition systems to verify signal paths and response. Educational demonstrations: illustrate waveform concepts and signal processing principles in classrooms or labs. Medical device testing: simulate ECG and other pulse waveforms to evaluate monitors, sensors, and data logging equipment.
