Wide frequency range and stable output Adjustable wave generation from 0.01 Hz to 100000 Hz enables precise applications across ultra low to frequencies with stable performance. accuracy and reliable results Input to output deviation is less than 1 percent, ensuring dependable calibration and testing results. Audible output behavior explained Speaker sound output is based on the frequency. At low frequencies, it is inaudible to human ears; when the frequency enters the audible range, the speaker will produce sound. Robust construction for reliability Made with a low temperature drift crystal oscillator and a precision tip to deliver robust performance and enhanced interference resistance. Plug and play The product is plug and play for easy setup and immediate use. Applications and use scenarios Laboratory and education settings: use for creating controlled waveforms to demonstrate frequency behavior, oscillator characteristics, and interference effects in physics or electronics courses. Audio equipment testing: test and evaluate frequency response, calibrate test rigs, and verify performance of speakers and related gear. Electronics development and debugging: generate precise reference signals for circuit testing, prototyping, and troubleshooting waveformrelated issues.
