Key benefits Simple square wave source with output amplitude approximately equal to the input voltage, making interfacing straightforward. Duty cycle remains stable during frequency changes, helping you maintain predictable signal behavior without manual adjustments. Fine frequency control via a built in multi turn potentiometer, with a clear option for the HV Version to cover 50 Hz to 6 kHz. What it does Output: square wave signal through the output terminal Amplitude: approximately equal to the input voltage Duty cycle: not adjustable; stays within about 50% to 65% as you adjust frequency Frequency control: achieved through a built in multi turn potentiometer Version: HV Version supports a frequency range of 50 Hz to 6 kHz Key specifications Output terminal: square wave signal Amplitude: approximately equal to input voltage Duty cycle: not adjustable; stable 50%–65% during frequency changes Frequency adjustment: built in multi turn potentiometer HV Version frequency range: 50 Hz to 6 kHz Why customers need it Provides a reliable timing reference for testing, debugging, and calibration without complex setup. The stable duty cycle during frequency changes reduces the need for constant waveform monitoring. Precise frequency tuning via a multi turn potentiometer enables accurate synchronization with other equipment. Use scenarios Electronics lab testing: generate a consistent square wave to drive test circuits and compare timing responses. Microcontroller and digital circuit debugging: use as a timing reference for pulse generation and timing analysis. Instrumentation calibration: apply a known square wave input to calibrate measurement equipment that requires a stable waveform.
