Sound level meter with octave-band
analyzer
SW 1000/SW 2000 devices belong to the new genera-
tion of sound level meters with octave-band analyzer.
The devices are equipped in the processor of ARM
architecture with FPU arithmetic coprocessor and
instead of fixed-point calculations they perform float-
ing-point calculations what definitely increases their
accuracy and stability. Its own noise is reduced by the
newly-designed analogue input module.
