The SVAN 958 is all digital, four channels 20 kHz signal analyser including Type 1
sound level meter (meeting IEC 61672) and vibration meter (meeting ISO 8041).
It is an ideal choice for the "Human Vibration" (according to the ISO 2631-1,2&5
and ISO 5349-1&2 standards) and noise measurements in the occupational
health and safety monitoring tasks. All required weighting filters, transducers and
adapters for triaxial Whole-Body and triaxial Hand-Arm vibration measurements
are available with this instrument.
Each of 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).
Three profiles allow parallel measurements with independently defined filters
and RMS detector time constants in every channel. Each profile/channel provides
"multidimensional" analysis of measured signal (like Leq, LMax, LMin, LPeak, SPL,
SEL in the case of sound measurements or RMS, Peak, VDV, MTVV in the case of
vibration measurements). Advanced time history logging, in non-volatile 32 MB
internal memory, 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.
Using computational power of its digital signal processor the SVAN 958
instrument can perform advanced frequency analysis simultaneously to the meter
- real time 1/1 or 1/3 octave analysis including statistical calculations
- FFT analysis including cross spectra
- sound intensity measurements.
Reverberation Time measurements, noise dose meter and rotation speed
measurements are also available as options for SVAN 958.
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 the SVAN 958. Instrument can be fully remotely controlled.
Instrument is powered by four AA standard or rechargeable NiMH batteries
(separate charger is required). 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.
