APPENDIX B. DATA FILE STRUCTURES
B.1 G
ENERAL STRUCTURE OF THE
SVAN 971
FILES
Each file containing data from the SVAN 971 instrument consists of several groups of words.
In the case of SVAN 971 (the internal file system rev.
1.11 ), there are two different types of files containing:
•
the results stored in the file in the instrument’s logger (cf. App. B.2);
•
setup data (cf. App. B.3).
Each file has the following elements:
•
SvanPC file header (cf. Tab. B.1.1)
•
file header (cf. Tab. B.1.2);
•
unit and internal software specification (cf. Tab. B.1.3);
•
calibration settings (cf. Tab. B.1.4)
•
user’s text (a header) stored together with the measurement data (cf. Tab. B.1.5);
•
parameters and global settings, common for all profiles (cf. Tab. B.1.6);
•
parameters for measurement trigger (cf. Tab. B.1.7);
•
parameters for logger trigger (cf. Tab. B.1.8);
•
parameters for Time-domain signal recording (cf. Tab. B.1.9);
•
parameters for Wave-file recording (cf. Tab. B.1.10);
•
special settings for profiles (cf. Tab. B.1.12);
•
display settings of the main results (cf. Tab. B.1.13)
•
header of the statistical analysis (cf. Tab. B.1.14);
•
header of the file from the logger (cf. Tab. B.1.15)
•
contents of the file from the logger (cf. Tab. B.1.16)
Other elements of the file structure are not obligatory for each file type stated above.
They depend on the file type (
SLM , DOSE METER , file from the logger) and on the setting of the
FULL STAT. These elements are as follows:
•
Header of the Summary Results Record (saved in Summary Results Record) (cf. Table B.1.17)
•
main results (saved in Summary Results Record) (cf. Tab. B.1.18_SLM, B.1.18_DM )
•
statistical levels (saved in Summary Results Record) (cf. Tab. B.1.19)
•
1/1 OCTAVE analysis results (saved in Summary Results Record) (cf. Tab. B.1.20)
•
1/3 OCTAVE analysis results (saved in Summary Results Record) (cf. Tab. B.1.21)
•
results of the statistical analysis (saved in Summary Results Record) (cf. Tab. B.1.22);
•
settings of the instrument saved in the setup file (cf. Tab. B.1.23);
•
file-end-marker (cf. Tab. B.1.24);
Below, all file structure groups are described separately in Tab. B.1.1
– Tab. B.1.23. The format used in
the columns, named Comment with the square parenthesis ( [xx, yy] ), means the contents
of the word with; xx is the most significant byte (MSB) and yy the lowest significant byte (LSB)
of the word. The format 0xnnnn means that the nnnn is four-digit number in hexadecimal form.
