C.2 SPECIFICATION OF SVAN 971 AS 1/1 OCTAVE AND 1/3 OCTAVE ANALYZER
The SVAN 971 instrument can operate as 1/1 Octave or 1/3 Octave analyzer conforms to the international
standards IEC 61260-1:2014 standard for the pass band filters.
Note: Simultaneously to the frequency analysis SVAN 971 operates as a Sound Level Meter!
See Chapters C.1 for specification.
