Key features Multiple waveform generation: provides square, sine, and triangle wave outputs for versatile testing and educational use. Adjustable amplitude control: output amplitude can be set from 0 to 3 V for sine and triangle waves, and up to 8 V for square waves, allowing alignment with different circuit requirements. Wide frequency range: capable of generating frequencies from 1 Hz to 1 MHz, supporting a broad set of testing scenarios. Low distortion: distortion remains under 1% at 1 kHz for sine and triangle wave outputs, ensuring reliable signal accuracy for measurements. Benefits and practical use Versatile tool for labs, classrooms, and hobby projects, enabling handson learning with multiple waveforms and adjustable levels. Flexible settings to match circuit needs without overdriving components, reducing risk of damage during testing. Accurate signal generation across a wide frequency span supports diverse experiments and equipment verification. Reliable performance with low distortion at common test frequencies enhances result consistency. Use scenarios Educational demonstrations and experiments: illustrate how different waveforms interact with filters, amplifiers, and DACs, while adjusting amplitude and watching circuit response. Opamp and filter characterization: apply sine and triangle signals across frequencies from 1 Hz to 1 MHz to observe gain, phase shift, and distortion. Digital and timing tests: use square waves at varying frequencies to examine timing behavior, signal integrity, and microcontroller I/O compatibility in a controlled test setup.
