C.3. SPECIFICATION OF SVAN 977A AS 1/1 OCTAVE AND 1/3 OCTAVE ANALYSER
SVAN 977A can operate as 1/1-octave or 1/3-octave analyser conforming to the international IEC 61260-
1:2014 standard for the pass band filters.
Note: Simultaneously to the frequency analysis SVAN 977A operates as Sound Level Meter! See
Chapters C.1 for specification.
Signal input
● SV12L preamplifier throughout ST02 adapter
● Maximum input voltage: SVAN 977A meets the requirements IEC 348 for the 2
nd
class device. The input
voltage shall not exceed the limits between -15 V and +15 V.
● Impedance: 10 G / 2 pF.
