Duty cycle remains non adjustable - The output duty cycle is not adjustable. During frequency changes the duty cycle stays stable, typically within 50% to 65%. Frequency control via built in potentiometer - Frequency is set with an integrated multi turn potentiometer. - H-Version frequency range: 50 Hz to 6 kHz. Output characteristics - The module provides an output square wave. - Amplitude of the output is approximately equal to the input voltage, enabling straightforward interfacing with logic level circuits. 2-3 practical use scenarios - Use scenario 1: Laboratory timing reference for digital circuits - Generate clock-like signals at various frequencies while maintaining a stable duty cycle, suitable for microcontroller timing tests and digital circuit verification. - Use scenario 2: Synchronization and gating in measurement setups - Use as a reference clock or trigger signal to synchronize instruments and data acquisition systems that require a predictable square wave waveform. - Use scenario 3: Logic-level circuit testing and calibration - Feed the square wave into logic devices where the output amplitude matches the input level, aiding direct interfacing and straightforward testing without additional level shifting.
