What Stands Out
Versatile Waveforms
Offers sine, triangle, square, and sawtooth waveforms, catering to diverse testing needs for audio and frequency applications, ensuring compatibility with a wide range of electronic projects.
Wide Frequency Range
Operates from 1Hz to 500kHz, providing flexibility for various signal generation tasks and making it suitable for both low-frequency audio applications and high-frequency experiments.
Portable Design
Compact and lightweight, this generator is travel-friendly, allowing users to conduct tests and experiments on the go without compromising functionality or performance.
Product Details
- 7 built-in shapes: Sine, square, triangle, ±sawtooth, noise, ECG. Toggle filter-silky sine or razor-sharp pulses on demand.
- 1 Hz – 500 kHz sine (flat to 200 kHz); 1 Hz – 20 kHz for other waveforms—usable beyond if extreme purity is not required
- 1 Hz resolution, settings auto-saved. Sine THD <1 % below 1 kHz, <0.5 % above. Crystal-based DDS stability—ideal for calibrating oscilloscope time-bases or probing amp frequency/impulse response
- 3.5 – 10 V DC input:Runs straight from any USB port (5 V recommended) or a single 3.7 V Li-ion cell (NOT included)
- 50 Ω output, ±10 V p-p amplitude, ±10 V DC-offset (defeatable). Square edge perfect for adjusting scope probes and attenuator compensation
- Field-friendly uses: Sweep amps, inject test signals, verify frequency/impulse response, or trim probe compensation—any bench, anywhere
