12.2.5 Signal Recordings on the PC

When projects including signal recording have been transferred into an Archive on a PC using

BZ-5503, then the recordings can be played back directly from BZ-5503.

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.
