SigAnal data
The FileType stored in the file header is “SigAnal “.
Header data
This file type uses the ‘File Header’ described in chapter “ File Header ” on page 303.
The following additional data is stored in the Header, following the default header:
 CursorHide: flag that indicates if the cursor are hidden.
 LabelX: the x-axis unit label string.
 LabelY: the y-axis unit label string.
 Pad: padding bytes for alignment ( not used ).
 XSizePhys: the physical width of the data range.
 YSizePhys: the physical height of the data range.
 XSizeUser: the width of the data range in the user interface.
 YSizeUser: the height of the data range in the user interface.
To the default file header with 64 bytes additional a block of 112 bytes is added.
The additional block contains display parameter used by the WAVECOM GUI for displaying the stored data
correctly.
NOTE: the following struct type could be used to extract the data header.
struct SigAnalData
{
char m_nCursorHide;
char m_strLabelX[40];
char m_strLabelY[40];
long m_Phis_xSize;
double m_Phis_ySize;
double m_User_xSize;
double m_User_ySize;
};
