| B&K 2250 Frequency Analysis Option - BZ 7223 | included with all our 2250 meters |
All our 2250 meters come with the frequency analysis software enabled for real-time measurements in 1/1- and 1/3-octave bands, making it a simple matter to obtain spectra in order to, for example, select hearing protection, qualify heat and ventilation systems, and assess tonality.The following frequency ranges are available:
1/1-octave spectra (centre frequencies 8 Hz to 16 kHz)
1/3-octave spectra (centre frequencies 6.3 Hz to 20 kHz)
In each band you have a full and unrivalled dynamic range from the noise floor in that particular band to 140 dB. That is a dynamic range generally in excess of 135 dB.
Spectra can be A-, C- or Z-weighted. Five spectra and full spectral statistics are measured and stored and, in addition, seven different LN spectra and instantaneous values are available for display. Two spectra, for example, a minimum and maximum spectrum, can be superimposed on the display. As a matter of course, all the broadband quantities measured by Sound Level Meter Software BZ 7222 are computed in parallel with the frequency analysis. Spectral analyses can be documented using notes and voice annotations.
If Sound Recording Option BZ 7226 is also enabled, you can record all or part of the measured signal.
