SVAN 979 Sound and Vibration Meter

SVAN 979 is a powerful and advanced real-time sound and vibration analyzer for use in acoustical engineering, high-priority monitoring, and safety applications. The SVAN 979 has features and sensitivity commonly found precision laboratory equipment but in a portable sound and vibration meter and analyzer. 

  • Type 1 IEC 61672:2002 sound level measurements
  • General vibration measurements (acceleration, velocity and displacement)
  • Three parallel independent profiles
  • 1/1, 1/3 octave real-time analysis
  • 1/6 or 1/12 octave real-time analysis
  • FFT real-time analysis 1600 lines in up to 22.4 kHz band
  • Time-domain signal recording
  • Advanced data logger including spectra logging and Audio Events Recording
  • Reverberation Time measurements
  • Pure tone detection
  • Acoustic loudness measurements
  • Advanced trigger and alarm functions
  • User programmable Band-Pass Filters

Large, easy to read color displaySVAN 979 can record a raw audio data to micro SD flash card in WAV format, so sources of noise can be played back and identified by listening (Time-domain SignalRecording). The Audio Events Recording function is very useful in measurements requiring unattended monitoring.

Moreover, the SVAN 979 is able to perform advanced measurement techniques like MLS, TDS etc. thanks to built-in sophisticated signal generator.

SVAN 979 is designed for easy communication with computers by built-in ports USB client and USB host. In practice it means full remote control over the instrument from the PC. Fast USB 1.1 interface (12 MHz) creates real-time link for the PC "front-end" application of the SVAN 979 instrument .

SvanPC+_VR viewer software provides easy local communication with PC, data transfer and instrument's settings configuration. This already advanced and user-friendly application can optionally be extended by SvanPC+_RC remote communication module (GPRS, LAN or WLAN transmission) and SvanPC+_EV software for environmental monitoring data processing.

These exceptional features make SVAN 979 the leading product for measurements in field (environmental monitoring). SVAN 979 is powered from 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.

SVAN 979 is a powerful and advanced single channel instrument for acoustic and vibration measurements. The list of the instrument features includes:

  • High accuracy sound and vibration measurements
  • Powerful frequency analysis package
  • Time-domain (WAV) and Audio Events recording to Micro SD card
  • Very high dynamic measurement range
  • Extremely flat frequency response (digitally compensated)
  • Range of interfaces (USB, Bluetooth, IrDA, RS232 and more)
  • USB Host port providing very flexible extension capabilities
  • GPRS and WLAN communication (USB Host port) ready
  • GPS time synchronisation
  • Super contrast color display
  • Built-in signal generator
  • Automatic windscreen and extension cable detection
  • All weather microphone protection with Community and Airport response.

SVAN 979 can record raw audio data to micro SD flash memory in WAV format allowing for play-back and identification of noise sources with the Time-domain signal recording. This feature is very useful in measurements requiring unattended monitoring.

SVAN 979 is able to perform advanced measurement techniques like MLS and TDS thanks to a built-in sophisticated signal generator. SVAN 979 is designed for easy communication with computers by built-in USB port and USB host allowing for full remote control over the instrument via PC.

SvanPC+_VR viewer software provides easy local communication with PC, data transfer and instrument's settings configuration. This advanced and user-friendly application can optionally be extended by SvanPC+_RC remote communication module (GPRS, LAN or WLAN transmission) and SvanPC+_EM software for environmental monitoring data processing. These exceptional features make SVAN 979 the leading product for measurements in-field (environmental monitoring).

SVAN 979 is powered from standard or rechargeable AA batteries. Optionally the instrument can be powered from the External DC power or USB interface.

Robust and light weight, the SVAN 979 provides exceptional features in a new generation of instrument.
