Optional Program Cards

NX-28WR

Makes it possible to measure sound pressure levels together with sound pressure waveforms during frequency analysis. This allows you to listen to specific events. You can also reanalyse recorded sound.

NX-28FT

This program card adds FFT analysis capability to NA-28, with an analysis frequency range of 20kHz and 8000 analysis lines.

NX-28BA

This program card is used for simple and easy measurement of airborne and floor impact sound insulation of buildings and reverberation time. Data is stored as text files. When used in conjunction with waveform recording card NX-28WR, sound waveforms during measurement can be recorded simultaneously.
