SVAN 979 is the most advanced and powerful single channel instrument for general acoustic and vibration measurements ever made. The list of the instrument outstanding features and functionalities includes:
- high accuracy sound and vibration measurements
- most 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)
- extremely flexible set of interfaces (USB, Bluetooth, IrDA, RS232 and more)
- USB Host port providing very flexible functional extensions capabilities
- firmware ready for GPRS and WLAN communication (USB Host port)
- GPS time synchronisation
- super contrast colour display
- built-in signal generator
- automatic windscreen and extension cable detection
- all weather microphone protection with Community and Airport response.


SVAN 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, instrument 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++ software provides an 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++_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. The powering of the instrument from the External DC power source or USB interface is also provided. Robust and light weight design accomplishe the exceptional features of this new generation instrument.
