Introduction

1.1 Overview

The SW 1000/SW 2000 gauges are a new generation of measuring instruments with
an octave analyser which meets the market requirements and is based on the basic
SW 1000/200 instrument. The meter meets the requirements of IEC standard and the
Chinese GB/T standard for measuring instruments with 1/1-octave analysers.
The SW 1000/SW 2000 gauge is a digital sound level meter developed and manufac-
tured by KERN. The instrument with a 24-bit analogue-digital converter with a very
high accuracy is a perfect choice for various measuring activities, such as measure-
ment of noise generated in the environment, by vehicles or in industrial applications.
The new types are equipped with a single-chip ARM processor with two cores
(DSP+ARM) and a floating-point co-processor, so they perform floating-point calcula-
tions instead of fixed-point calculations, which considerably improves their accuracy
and stability. The re-designed input module additionally reduces own noises and en-
hances the linear measuring range. The new algorithm supports only one measuring
range which includes a dynamic range above 120 dB, but despite that it still meets
the requirements of the standard.
The SW 1000 meter is a Class 1 gauge, and the SW 2000 is a Class 2 gauge.
