12.2.1 Waveform export files
Waveforms can be stored in XML, CSV, or BIN format.
Reloading waveforms: Restrictions
To reload waveform data as a reference waveform, it must be stored in BIN format.
If multiple acquisitions of one waveform are exported (Data logging or Multiple wave-
forms), only the first acquisition can be reloaded.
If the signal is a spectrum, reloading is only possible for waveforms with "Magnitude
unit" = Linear. Waveforms with logarithmic unit cannot be reloaded.
Data of all waveforms is saved in two files. One file contains the waveform data values
and is indicated by *Wfm.* in the filename. The second file contains the header data,
for example, time scale, vertical scale, vertical and horizontal positions, interpolation
mode and much more. Header data is required to restore the waveform from data, or
to analyze the data values of the data file.
12.2.1.1 Header files
The header files of XML and BIN waveform files are written in XML format. The header
files of CSV waveform files are written in CSV format. You can open the header files
and use their information for data analysis.
CSV header files only contain the property names and values, one property per row.
Resolution:1e-010:
RecordLength:1000:
XML header files contain more information than CSV header files. The additional infor-
mation is required to reload the stored waveforms with their correct settings.
