SVAN 958
Four Channels Sound and Vibration Analyser

SVAN 958

Four Channels Sound and Vibration Analyser with time domain signal recording.
SVAN 958 is a fully digital, four channels 20 kHz signal analyser including Type 1 sound level meter (meeting IEC 61672) and vibration meter (meeting ISO 8041:2005).
Simultaneously to the meter mode, SVAN 958 can perform advanced frequency analysis including 1/1 or 1/3 octave analysis, FFT analysis including cross spectra's and sound intensity measurements. Reverberation Time measurements, noise dose meter and rotation speed measurements are also available. Moreover, SVAN 958 has an exceptional feature of time domain signal recording to the USB memory stick.

  

SVAN 958 ORDERING INFORMATION

SVAN 958 is an ideal choice for the "Human Vibration" (according to the ISO 2631-1,2&5 and ISO 5349-1&2 standards). It is offered with all required weighting filters and comprehensive range of equipment for measuring hand-arm and whole-body vibration.

SVAN 958 uniquely does the analysis in four channels. Each of the four channels can work simultaneously with independently configured input (transducer type), filters and RMS detector time constants (e.g. simultaneous three axis measurement of the Whole-Body vibration and noise dose).

Recently SVAN 958 has been improved by implementation of the special KB filter for building vibration measurements meeting the DIN 4150 standard.

SVAN 958 can also perform noise measurement with accuracy of Type 1. Thanks to its four channels it can measure sound by the use of four independent microphones in the same time.
What is more, in sound meter mode, each channel uses three independently defined profiles which means that SVAN 958 can perform "multidimensional" analysis of measured signal in every of four channels. In practice it gives a user the possibility to obtain Leq, LMax, LMin, LPeak, Spl, SEL with different weighing filters in the same time.

Very powerful measurement capability is supported by the advanced time history logging in non-volatile 32 MB internal memory. SVAN 958 is also equipped with USB port which allows to storage data in the USB Memory Sticks of size even 8 GB.

Together with SVAN 958 we provide the SC 16 cable for the connection with the PC. Easy data downloading to the PC is ensured by the SvanPC+ software (base module free of charge). Fast USB 1.1 interface (12 MHz) creates real time link for the PC "front-end" application of the SVAN 958. Instrument can be fully remotely controlled. Optionally, SVAN 958 can be equipped with RS 232 or IrDA port.

SVAN 958 is powered from NiMH standard or rechargeable AA batteries. The powering of the instrument from the External DC power source or USB interface is also provided.

Robust and light weight design accomplishes the exceptional features of this new generation instrument.
