Appendix B. DATA FILE STRUCTURES
There is a number of files generated by the SV 200A instrument automatically and saved in the internal
non-removable SD-card. Some of these files are binary, other are ASCII one. In the case of SV 200A
(the internal file system rev. 1.03), there are five different types of files:
• SVL - a binary file which contains miscellaneous results (cf. B.1 and B.2);
• CSV - an ASCII file which contains miscellaneous results (cf. B.3);
• SVT - a binary file with instrument’s setup data (cf. B.4).
• SVA - an ASCII XML file with advanced alarm setup data (cf. B.5)
• TXT - an ASCII file named “C*.txt” which contains calibration and system check history data
(cf. B.6)
• LOG - an ASCII file which contains miscellaneous information about instrument’s status used for
debugging purpose (cf. B.7Błąd! Nie można odnaleźć źródła odwołania.)
B.1 GENERAL STRUCTURE OF THE SVL FILE
Each SVL file containing data from the SV 200A instrument consists of several blocks and logger
records. A block is rather a header with static information which usually appears at the beginning of the
file or data which may present anywhere in the file. Each block has its unique ID and length specified.
A logger record can be a time history (TH) results block, record of audio data, marker information, pause
information or a special block containing summary results (SR), meteo data, GPS data etc.
Each file has the following obligatory blocks:
• SvanPC++ file header (cf. Table B.1.1)
• file header (cf. Table B.1.2);
• instrument and internal software specifications (cf. Table B.1.3);
• user’s text (a header) stored together with the measurement data (cf. Table B.1.4);
• parameters and global settings, common for all profiles (cf. Table B.1.5);
• parameters for measurement trigger (cf. Table B.1.6);
• parameters for logger trigger (cf. Table B.1.7);
• parameters for Time-domain signal recording (cf. Table B.1.8);
• parameters for Wave-file recording (cf. Table B.1.9);
• Extended I/O settings (cf. Table B.1.10);
• special settings for profiles (cf. Table B.1.11);
• RTF parameters (cf. Table B.1.12);
• main results saved as Summary Results (SR) Record (cf. Table B.1.13);
• header of the file from the logger (cf. Table B.1.20);
• contents of the file from the logger (cf. Table B.1.21);
Other blocks of the file structure are not obligatory. They depend on the instrument’s current mode and
connected accessories. These blocks are as follows:
• statistical levels saved in the Summary Results record (cf. Table B.1.14);
• header of the statistical analysis (cf. Table B.1.15);
• results of the statistical analysis (cf. Table B.1.16);
• 1/1 OCTAVE analysis results saved in the Summary Results record (cf. Table B.1.17);
• 1/3 OCTAVE analysis results saved in the Summary Results record (cf. Table B.1.18);
• settings of the instrument saved in the setup file (cf. Table B.1.19);
• Meteo data - (cf. Table B.1.22);
• Alarm parameters - (cf. Table B.1.23);
