Generally, the format of this ASCII file can be processed by spreadsheet calculation
programs, e.g. MS-Excel. Different language versions of evaluation programs may
require a different handling of the decimal point. Thus you can define the decimal sep-
arator to be used (decimal point or comma, see
If the spectrogram display is selected when you select the "ASCII Trace Export" soft-
key, the entire histogram buffer with all frames is exported to a file. The data corre-
sponding to a particular frame begins with information about the frame number and the
time that frame was recorded.
