OpenTest
OpenTest is a next-generation platform designed for engineers, researchers, and manufacturers seeking precision, flexibility, and innovation in acoustic and vibration testing. Built on three core principles—Openness, AI-Driven Intelligence, and Boundless Compatibility—we empower industries like consumer electronics, automotive NVH, industrial diagnostics, and academic research to redefine quality control, accelerate R&D, and streamline production.

Free Core Features
Access essential tools like frequency response, phase analysis, and distortion testing—completely free for students, startups, and researchers.
Monitor
Continuous waveform monitoring and FFT spectrum analysis enable real-time identification of signal anomalies, such as clipping, clock jitter, and other issues. It simultaneously tracks key metrics, including RMS level, THD, SND, and frequency response, with configurable high-pass/low-pass filters and A/C/Z frequency weighting.
Dynamic Tracking
Instant Anomaly Detection
Octave Analysis
The octave analysis function provides two core tools: FFT-based fast analysis and filter-based standard analysis. Within a set recording period, the system can simultaneously perform multi-channel analysis with different octave widths on the acquired waveform, flexibly adapting to diverse testing scenarios. Users can customize the frequency range according to their needs, apply A/C/Z frequency weightings, and conduct synchronous analysis of multiple octave types including 1/1oct., 1/3oct., 1/6oct., 1/12oct., and 1/24oct. The analysis results can be intuitively presented in three forms: bar charts, line charts, and tables, facilitating data interpretation and storage.
Real-time Analysis
Sweep Analysis
The sweep analysis function offers two core modes: continuous sweep and stepped sweep, enabling dynamic sweep testing of signals within a set frequency range. The system can automatically generate sweep signals based on preset parameters (such as sweep rate or step interval), synchronously collect response data from the measured object, and calculate and display key indicators in real time—including amplitude-frequency characteristics and phase-frequency characteristics. It also supports multi-channel parallel testing, effectively adapting to multi-dimensional testing scenarios.
