Svan 958 Sound and Vibration Analyser

This is the Svan 958A Class 1 Four-Channel Sound and Vibration analyser which is dedicated for all applications that require simultaneous class 1 sound and vibration assessment. Each of the four input channels can be independently configured for sound or vibration detection with different filters and RMS detector time constants which gives users an enormous measurement flexibility.

A real advantage of this instrument is the capability to perform advanced analysis simultaneously to the level meter mode. This allows the user to obtain broadband results such as Leq, RMS, LMax, LMin, LPeak together with four-channel analysis like FFT or octave band analysis.

Available analyser functions include FFT, 1/1 or 1/3 octave, cross spectra, sound intensity, RT60 and more.

There is 4-channel time-domain signal recording to .wav format as well as an exceptional feature. All of the measurement results are stored in a non-volatile 32 MB internal memory or a USB memory stick and they can be easily downloaded to a PC with SvanPC++ software. It can be offered with GPRS modem or LAN and WLAN connection module.

These interfaces provide easy remote access to instrument settings and data over Internet and local area network together with SvanPC++ RC remote communication software. It is powered from four AA standard or rechargeable batteries as well as from the external DC power source or USB interface. There is a robust case and lightweight design which accomplish the exceptional features of this new generation instrument.
