C.4 SPECIFICATION OF SV 973 AS 1/1 OCTAVE AND 1/3 OCTAVE ANALYZER
Statement of performance
SV 973 can operate as 1/1-octave or 1/3-octave analyser which meets requirements of the international
IEC 61260-1:2014 standard for the pass band filters for the Class 1 instruments. For sound analysis, its
accuracy results from the accuracy of the Sound Level Meter - see Chapters C.1 for specification.
Note: Simultaneously to the frequency analysis SV 973 operates as a Sound Level Meter - see
Chapters C.1 for specification.
Signal input
SV 973 microphone input throughout the SL 973 adapter
Maximum input voltage:
SV 973 meets the requirements of IEC 348 for the 2nd Class
devices. The input voltage shall not exceed the limits
between 0 V and +3 V.
SL 973 the input voltage shall not exceed the limits between -3 V
and +3 V.
Impedance:
SV 973 differential input: ≤ 94 k, ≤ 50 pF each.
SL 973 ≤ 10900 , ≤ 30 pF, single ended input.
