Svantek SVAN 979 Class 1 Sound & Vibration Analyzer
The SVAN 979 Class 1 Sound & Vibration Analyzer is our flagship device. Your first impression
will be the amazing OLED display which features excellent visibility in all light conditions. The
instrument’s lightweight and durable aluminium housing not only gives a sense of a firm grip but
also protects the valuable electronic device from damage and any influence from electromagnetic
interference.
The SVAN 979 has a very large dynamic range of measurement – over 110dB. It’s high-quality
GRAS 40AE microphone allows measurement in the frequency range starting as low as 3 Hz.
The measurement path has been designed to allow the use of other microphones should you
want to measure very low frequencies or very high levels of noise. The microphone preamplifier
has also been reinforced with a collar to protect against mechanical damage. One amazing
feature of the SVAN 979 is that if you disconnect the microphone preamplifier then you can use
the instrument for vibration measurements – simply connect up a cable and a vibration sensor .
The SVAN 979 has an extensive range of hardware and firmware add-ons that includes built-in
Bluetooth ® , windscreen infrared detector, direct connections to GPS module, GPRS or Wireless
LAN modem or the totally unique built-in vibration shock sensor that warns the user whenever
the instrument itself is exposed to vibrations that may influence the noise measurements.
Two USB connectors allow for the simultaneous operation of USB pen-drives and
communication with the computer.
Usage of this number of advanced features at the same time is possible as the instrument has
two high-speed digital signal processors. For example, the SVAN 979 is capable of measuring 2
ms steps of time history, logged simultaneously to audio recording (with 48kHz sampling) and
real-time frequency analysis. Only the SVAN 979 can meet such a challenge. All data is stored
on a microSD card of any capacity (default is 8GB) .
It is also important to note that unlike other brands which recalculate FFT spectrum to octave
bands, the SVAN 979 performs frequency analysis in real-time, whether in octaves, third octaves
all the way up to 1/12 octaves.
Setting up such advanced measurements can be very complicated but not in the SVAN 979. The
intuitive menu structure of this instrument has been designed to make the measurement
experience a pleasure.
