BSWA 308 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.
