Key benefits Provides a square wave output with amplitude approximately equal to the input voltage, enabling direct drive of many digital circuits without extra buffering. Duty cycle is not adjustable; during frequency changes the output maintains a stable duty cycle in the 50% to 65% range, supporting predictable timing. Frequency is adjustable through a builtin multiturn potentiometer, with an adjustment range of 50 Hz to 6 kHz for versatile use. Simple and reliable signal source suitable for benchtop testing and standard lab work. Key specifications Output: square wave at the output terminal Amplitude: approximately equal to input voltage Duty cycle: not adjustable; remains stable between 50% and 65% as frequency is adjusted Frequency control: builtin multiturn potentiometer Frequency range: 50 Hz to 6 kHz Typical applications Clock and timing signals for microcontrollers and digital logic circuits requiring a square wave with amplitude close to the input voltage Testing and characterization of logic gates, flipflops, and RC networks where a stable duty cycle is beneficial during frequency sweeps Educational demonstrations and laboratory experiments that require a simple, adjustable square wave source within 50 Hz to 6 kHz Notes The device delivers a square wave with amplitude close to the input voltage and a nonadjustable duty cycle that remains stable as frequency changes, with frequency adjustment via an internal multiturn potentiometer covering 50 Hz to 6 kHz.
