Adjustable pulse wave generator and audio resonator — key benefits and features Key benefits Wide, continuous frequency coverage from 0.001 Hz to 200 kHz covers ultralow, subaudio, audio, and ultrasonic testing without swapping instruments. Built-in resonance at 7.83 Hz allows repeatable access to that specific low-frequency point for research or verification tasks. Generates both pulse (adjustable pulse waves) and pure sinusoidal outputs to support functional testing, filter tuning, and signal-conditioning workflows. Acts as an audio resonator throughout its specified range, enabling direct testing of transducers, amplifiers, filters, and acoustic systems. Simplifies bench setups by combining ultralow-frequency capability and audio-resonator function in a single device. What the product does (functions and performance) Adjustable pulse wave generator: produces pulse/modulated waveforms across 0.001 Hz–200 kHz for modulation, timing, and excitation needs. Sinusoidal output: provides clean sine waves within the same frequency range for frequency-response measurements and component characterization. Resonance feature: includes a specified resonance at 7.83 Hz useful for targeted resonance testing or experiments that require access to that frequency. Audio resonator function: operates as an audio resonator across the stated range, suitable for verifying resonance behavior in speakers, microphones, and acoustic circuits. Compatibility and integration Outputs are suitable for use with standard measurement and audio equipment that accept analog input signals within 0.001 Hz–200 kHz (oscilloscopes, audio analyzers, amplifiers, data acquisition systems). Designed to be integrated into laboratory, development, and production test setups where pulse and sine sources across ultralow to ultrasonic ranges are required. Can be used alongside filters, preamps, power amplifiers, and sensors without changing the generator to cover different frequency bands. Practical attributes (size, material, durability) Intended for bench and test environments where a single, wide-range signal source reduces instrument count and setup time. Constructed for routine test use and repeatability; suitable for lab, workshop, or field measurement tasks where ultralow-frequency generation is needed. (Note: exact dimensions, connector types, and housing materials depend on the specific model variant.) Use scenarios (how customers apply this device) 1) Laboratory signal source: generate precise sine and pulse inputs from 0.001 Hz through audio and ultrasonic bands to characterize filters, sensors, and analog electronics. 2) Acoustic and transducer testing: drive speakers, subwoofers, microphones, and resonant enclosures to measure frequency response, resonant peaks, and system behavior across subaudio and audio bands; use the 7.83 Hz resonance point when low-frequency response is a focus. 3) Research and control systems: provide ultralow-frequency excitation for slow-control cycles, resonance experiments, or environmental/physiological studies that require stable output at or near 7.83 Hz. How it solves common problems Eliminates the need for multiple generators by covering an extensive frequency span in one device. Delivers both pulse and sine outputs so designers and technicians can test both time-domain and frequency-domain behavior without reconfiguring sources. Provides direct access to an established resonance frequency (7.83 Hz), making it faster to reproduce and document experiments or product tests that target that point. Customer considerations Verify the specific model’s connectors, amplitude range, and control interfaces to ensure direct compatibility with your existing test equipment. Use appropriate coupling, filtering, and amplification when connecting to high-power audio systems or sensitive measurement inputs to protect equipment and preserve waveform integrity.
