Each file containing data from the SVAN 977 instrument consists of several groups of words.
In case of SVAN 977, there are two different types of files containing:
• the results stored in the file in the instrument’s logger (see Chapter B.2)
• setup data (see Chapter B.3).
Each file has the following elements:
o SvanPC file header (cf. Table B.1.1)
o file header (cf. Table B.1.2)
o unit and internal software specification (cf. Table B.1.3)
o calibration settings (cf. Table B.1.4)
o user’s text (a header) stored together with the measurement data (cf. Table B.1.5)
o parameters and global settings, common for all profiles (cf. Table B.1.6)
o parameters for measurement trigger (cf. Table B.1.7)
o parameters for logger trigger (cf. Table B.1.8)
o parameters for Time-domain signal recording (cf. Table B.1.9)
o parameters for Wave-file recording (cf. Table B.1.10)
o extended I/O parameters (cf. Table B.1.11)
o special settings for profiles (cf. Table B.1.12, Table B.1.13)
o RTF parameters (cf. Table B.1.14)
o marker parameters (cf. Table B.1.15)
o header of the statistical analysis (cf. Table B.1.16)
o header of the 1/x Octave analysis (cf. Table B.1.17)
o header of the statistical analysis performed in 1/x Octave mode (cf. Table B.1.18)
o header of the FFT analysis (cf. Table B.1.19)
o RT60 parameters (cf. Table B.1.20)
o header of the logger file (cf. Table B.1.21)
o contents of the file from the logger (cf. Table B.1.22)
Other elements of the file structure are not obligatory for each file type stated above.
They depend on the configuration of the instrument. These elements are as follows:
• main results (saved in Summary Results Record) (cf. Table B.1.23, Table B.1.24)
• statistical levels (saved in Summary Results Record) (cf. Table B.1.25)
• 1/x Octave analysis results (saved in Summary Results Record) (cf. Table B.1.26)
• FFT analysis results (saved in Summary Results Record) (cf. Table B.1.27)
• results of the statistical analysis in profiles (saved in Summary Results Record) (cf. Table B.1.28)
• results of the statistical analysis in performed in 1/x Octave mode (saved in Summary Results Record)
(cf. Table B.1.29)
• RPM results (saved in Summary Results Record) (cf. Table B.1.30)
• METEO data (saved in Summary Results Record) (cf. Table B.1.31)
• RT60 results (cf. Table B.1.32)
• RT60 averaged results (cf. Table B.1.33)
• settings of the instrument saved in the setup file (cf. Table B.1.34)
• setup file end marker (cf. Table B.1.35)
