1 INTRODUCTION

SVAN 958A Class 1 Four-channel Sound & Vibration

Analyser is dedicated for all applications that require

simultaneous class 1 sound and vibration assessment.

Each of four input channels can be independently

configured for sound or vibration detection with

different filters and RMS detector time constants giving

users an enormous measurement flexibility. The real

advantage of SVAN 958A is the capability to perform

advanced analysis simultaneously to the level meter

mode. In practise this allows the user to obtain broad-

band results such as Leq, RMS, LMax, LMin, LPeak

together with four-channel analysis like FFT or octave

band analysis.

SVAN 958A as sound meter meets IEC 61672-1:2013

and as vibration meter meets ISO 8041-1:2017. All

required weighting filters, transducers and adapters for

triaxial Whole-Body and triaxial Hand-Arm vibration

measurements (VM) are available with this instrument.

Additionally, in case of sound measurements (SM), each channel calculates simultaneously the results in three

independent profiles.

Advanced time-history logging, provides very powerful measurement capability. The external USB Memory

Stick extends this facility almost unlimitedly. Results can be easy downloaded to any PC using standard USB

(or optional RS 232 and IrDA) interface and SvanPC software.

Reverberation Time measurements, noise dosimeter and rotation speed measurements are available as

options for the SVAN 958A instrument.

The time-domain signal recording on the external USB memory stick is also available as an exceptional option.

Fast USB 1.1 interface (12 MHz) creates real time link for the PC "front-end" application of SVAN 958A. The

measurement results can be downloaded to PC using the above mentioned interfaces.

The instrument is powered by four AA standard alkaline or rechargeable batteries (i.e. NiMH –separate charger

is required). Powering the instrument from the external DC power source or the USB interface

is also possible. Robust and lightweight design accomplishes the exceptional features of this new generation

instrument.

The Whole-Body vibration measurement is now even easier thanks to the SV 38 seat-accelerometer which can

be placed directly on the seat-cushion, on the floor or fixed to the back of the seat.

The SV 50 set with triaxial accelerometer enables Hand-Arm vibration measurements regardless of the type of

evaluated tool.

Additionally, for measurements of very high impulse vibration the special adapter SA 55, with low pass

mechanical filter protecting accelerometer from DC shift effect is available. Evaluation of the grip force will be

possible with the dedicated “integrated adapter” SV 105 (under development).
