Features

Class 1 accuracy

Certified measurement for demanding projects

SVAN 958A performs simultaneous Class 1 noise and vibration analysis up to 20 kHz. The instrument meets the standards required for engineering, environmental, and compliance-critical applications.

Four-channel flexibility

Independent configuration and advanced analysis

Each channel can be configured separately for sound or vibration with custom filters and time constants. SVAN 958A performs simultaneous FFT, octave, and broadband analysis, including cross spectra, RT60, and sound intensity.

Building Vibration Mode

Simultaneous velocity and acceleration analysis

SVAN 958A measures velocity and acceleration in real time, automatically identifying dominant frequencies. Each input supports mono- or triaxial sensors, enabling flexible setups for structural and ground vibration monitoring.

Multi-channel frequency analysis

Advanced diagnostics for complex acoustic and vibration tasks

SVAN 958A performs simultaneous four-channel analysis in 1/1 and 1/3 octave bands, FFT, and cross spectra. Its processing power supports detailed investigations across sound and vibration domains.
