SVAN 979

SVAN 979


The SVAN979 is our flagship sound & vibration analyzer. Your first impression will be the amazing OLED display which features excellent visibility in all light conditions. The instrument’s lightweight and durable aluminum 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 SVAN979 has a very large dynamic range of measurement – over 110dB . It’s high-quality GRAS40AE 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, ultrasounds 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 SVAN979 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 SVAN979 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 WiFi 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. The USB connection also allows for audio streaming where the time signal is transferred to the computer and written in the form of a wav file for further analysis.

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 SVAN979 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 SVAN979. The intuitive menu structure of this instrument has been designed to make the measurement experience a pleasure.
