Monitors & Meters

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

Sweep Analysis

This function utilizes logarithmically varying sweep signals to extend energy accumulation time in low-frequency ranges, ensuring measurement accuracy. At the same time, it significantly improves test efficiency. It enables fast and reliable testing for applications such as resonance peak detection in speakers, phase continuity analysis in headphones, and frequency response flatness evaluation in amplifiers. Results automatically comply with industry standards and generate professional test reports. It is an indispensable tool for audio R&D, production, and quality control.

Full-range Rapid Measurement

Sound Power Testing

This solution supports sound pressure-based sound power measurement, fully compliant with international standards ISO 3744 (Engineering Method), ISO 3745 (Precision Method), and ISO 3746 (Survey Method), meeting various accuracy requirements in different scenarios. It is suitable for R&D and quality control in consumer electronics, automotive audio systems, and professional audio equipment.
