BSWA308 Sound Level Meters

BSWA 308/BSWA 309 are octave sound level meters updating the dual-core (DSP+ARM) architecture to single chip ARM with float point unit, and updating all fix-point calculation to float-point, which signif cantly improves the accuracy and stability. Re-design analog front end circuit also lower the noise floor and linear range of product.

BSWA 308 is Class 1 and BSWA 309 is Class 2. Both instruments have certificated by the China CPA (Certification of Pattern Approval) and CMC (China Metrology Certification).

Single chip high speed ARM with FPU USB port function implemented
White backlight LCD Update firmware via USB (also power supply)
Integral period from 1s~24h Timer feature support auto measurement
0.1s, 0.2s, 0.5s logger step added Internal GPS (option) with GPS timing
5 templates to save user setting Single range to cover 123dB dynamic range
B-weighting added to meet ANSI standard Reduce the noise floor (only for Class 1)
Automatic power on with external supply, ease of integration Upper limit of measurement: 136dBrms/139dBpeak (40mV/Pa)
