CHAPTER 12
Signal Recording (Optional Module)

Signal Recordings can be input to the Brüel & Kjær PULSE Multi-Analyzer platform for further
analysis – please contact your local Brüel & Kjær representative for further information.
Note: When recording signals for further analysis in PULSE, be sure to record the Z-weighted
signal and select Automatic Gain Control to Off under the Signal Recording parameters and
select the Recording Quality to match your needs for frequency content – see details on sampling
frequency in Appendix A.
When Automatic Gain Control is set to Off , then the calibration information is stored in the wave
files – allowing PULSE to analyse the signal recordings, taking the calibration into account.
Note: Other sound players than BZ-5503 might not be able to amplify “24-bit per sample”
wav-files enough to hear weak sounds. If this is needed, then use 16-bit per sample.
