The Svan 977 is a high end piece of equipment in the sound and vibration industry, it is a type 1 instrument that meets the environmental monitoring of occupational heath and safety monitoring standards. It has extremely new and high tech hardware which allows the measurement of ultra sound frequencies in the 40kHz band!
The SVAN 977 can provide broadband results and all the standard weighting filters and also offers a time history logging capability providing broadband results and spectra with adjustable double (long and short) logging steps.
Its ability to record audio means it can be performed simultaneously with time history logging as either a separate wave file or as audio events inside time history files. Measurement results are recorded in three acoustic or vibration profiles enabling measurements to be performed with 3 different filters (e.g. A, C, Z) and 3 different detector time constants (e.g. Fast, Slow, Impulse).
Measurement data is stored on a µSD card and can be easily downloaded to a PC using SvanPC++ software over either USB or RS 232 interfaces.
The powerful DSP (digital signal processor) used in the SVAN 977 instrument can simultaneously operate in meter mode and perform real-time 1/1 or 1/3 octave analysis including statistical calculations. Additional functions like real-time FFT analysis and Rotation Speed Measurement are also available.
