Portable and ready: lightweight, compact design for easy transport. Dual power options — use the included power adapter or the builtin rechargeable lithium battery — so you can work at a bench or in the field without interruption. Accurate frequency control: sine wave output adjustable from 01Hz to 500kHz, with adjustable frequencies available for other waveforms. Precise tuning helps you reproduce test conditions and verify circuit behavior reliably. Simple to use for any skill level: intuitive controls and clear settings make it quick for beginners to generate the signals they need, while giving experienced users the control required for detailed testing and troubleshooting. Practical compatibility and performance: designed to integrate with common electronic projects and lab setups. The compact housing protects internal components while keeping the unit easy to carry and store. Key benefits at a glance: Eliminates the need to run power lines onsite thanks to the rechargeable lithium battery. Wide sinewave frequency range covers lowfrequency timing tests up to frequency component checks. Straightforward interface reduces setup time and learning curve, so you can focus on measurements and repairs. Typical applications Circuit testing and debugging: generate controlled signals to check amplifiers, filters, oscillators, and other modules. Prototyping and development: produce repeatable waveforms for sensor inputs, microcontroller testing, or signal conditioning verification. Education and lab work: a convenient tool for electronics classes and experiments where reliable, adjustable waveforms are required. What you'll notice in use Compact, lightweight footprint for easy storage and transport. Dual power flexibility for continuous bench use or portable field work. Precise frequency adjustment for consistent, repeatable test results.
