Square Wave Signal Generator Testing Module 1Hz-150kHz

Compact Square Wave Signal Generator for Precise Testing

This square wave signal generator is designed for accurate, repeatable testing of electronic circuits in the lab, workshop, or classroom. With a wide working voltage of 3.3-30 V and a frequency range from 1 Hz to 150 kHz, it offers flexible integration into a variety of DC-powered test setups. The clear digital display and intuitive button controls make configuration straightforward, even during detailed troubleshooting.

The generator outputs square waves with adjustable frequency and duty cycle, allowing you to simulate clocks, pulse trains, and control signals for microcontrollers, driver circuits, and other digital electronics. Frequency is divided into four selectable ranges for fine resolution, and settings are easily adjusted via four dedicated keys. Short presses allow precise single-step changes, while long presses enable rapid adjustment when scanning across a broader range.

Why It's a Smart Choice

• Wide operating range - 3.3-30 V working voltage and 1 Hz-150 kHz frequency range support a broad spectrum of low-voltage electronic projects and test scenarios.
• Accurate, readable output - Approximate 2% frequency accuracy and an easy-to-read display help ensure you can set and verify test conditions quickly and confidently.
• Compact and easy to integrate - Measuring just 7.8 × 4.2 × 2.6 cm and drawing approximately 5-30 mA output current, the module fits neatly into benchtop setups, DIY rigs, and portable test kits.
