B.1. STRUCTURE OF THE SVAN 958A FILE
Each file containing data from the SVAN 95x instrument consists of several groups of words. In the case of
the SVAN 958A there are some different types of files that contain:
• the measurement results from the Level Meter mode (cf. App. B.2);
• the results from 1/1 OCTAVE analysis (cf. App. B.3);
• the results from 1/3 OCTAVE analysis (cf. App. B.4);
• the results from the FFT analysis (cf. App. B.5);
• the results from the Level Meter mode stored in the file in the instrument’s logger (cf. App. B.6 and App.
B.10);
• the results from 1/1 OCTAVE or 1/3 OCTAVE analysis stored in the file in the instrument’s logger
(cf. App. B.7 and App. B.10);
• the results from the FFT analysis stored in the file in the instrument’s logger (cf. App. B.8 and App. B.10);
• the setup data of the instrument (cf. App.B.9);
• the results coming from RT60 measurement (cf. App. B.10);
• the averaged results of RT60 measurements (cf. App. B.11);
• time-domain signal saved in the logger file of the instrument (cf. App. B.12 and App. B.14).
Each file has the following elements:
• a file header (cf. Tab. B.1.1);
• the unit and internal software specification (cf. Tab. B.1.2);
• the marker for the end of the file (cf. Tab. B.1.25).
The other elements of the file structure are not obligatory for each file type stated above.
They depend on the file type (LM, 1/1 OCTAVE, 1/3 OCTAVE, RT60 or FFT analysis, file from the logger,
setup file). These elements are as follows:
• the parameters and global settings, common for all channels (cf. Tab. B.1.3);
• the hardware settings for channels (cf. Tab. B.1.4);
• the software settings for channels (cf. Tab. B.1.5);
• the VECTOR measurement settings (cf. Tab. B.1.6);
• the 1/1 OCTAVE or 1/3 OCTAVE analysis header (cf. Tab. B.1.7);
• the hand-arm and whole-body vibration dose measurement settings (cf. Tab. B.1.9);
• the main results (cf. Tab. B.1.10);
• the selected statistical levels in channels (cf. Tab. B.1.11);
• the results coming from 1/1 OCTAVE analysis (cf. Tab. B.1.12);
• the results coming from 1/3 OCTAVE analysis (cf. Tab. B.1.13);
• the totals description in 1/1 OCTAVE or 1/3 OCTAVE analysis (cf. Tab. B.1.16);
• the user-defined filter description (cf. Tab. B.1.17);
• the header of the FFT analysis (cf. Tab. B.1.8);
• the results of the FFT analysis (cf. Tab. B.1.14);
• the header of the statistical analysis (cf. Tab. B.1.18);
• the results of the statistical analysis (cf. Tab. B.1.19);
• the statistical analysis results performed in 1/1 OCTAVE or 1/3 OCTAVE mode (cf. Tab. B.1.20);
