Output waveforms: 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. Main technical parameters: Power supply: DC 49 V. DC5 V is recommended when using an adapter, 3.7 V lithium battery is recommended when using battery power. Key benefits: A broad waveform library enables versatile testing of analog, digital, and mixedsignal circuits with a single instrument. Flexible power options support both benchtop use with an adapter and portable use with a battery. Clear, repeatable waveform generation facilitates accurate validation of signal paths, filters, amplifiers, and data converters. Applications and use scenarios: Electronics lab bench testing: generate reference waveforms to verify DAC/ADC performance, amplifier response, and filter behavior during circuit development. Education and demonstrations: illustrate fundamental waveform concepts and signal behavior for students in electronics courses. Medical device development and testing: simulate ECG and other pulse shapes to evaluate signal processing hardware and software in prototypes. Notes: Powering options are compatible with DC supplies in the 4–9 V range; for adapters use 5 V, and for battery operation use a 3.7 V lithium battery as recommended.
