Example File
The following multi-page illustration shows the contents of a simple measurement file (of the
SDF 1.) It defines just one trace. The trace’s Y-axis values are contained in a vector of data at the end of
the file (in the record SDF_YDATA_HDR). The trace’s X-axis values are calculated from information in
the record SDF_DATA_HDR.
