Storage and Offline Working on Traces
Traces can be stored and are available off-line for subsequent evaluations, con-
trols, and comparisons or documentation.
Storing can occur in two ways:
• with "Save Trace" (extension *.trc): The trace is stored in a analyser format. It
can be opened and processed with the analyser software afterwards.
• with "Trace Export (extension *.tsv): The trace is stored in a "tabulator separated
value" format. So it can be exported into an Excel sheet.
Opening: You can "open" a stored trace off-line by a click on the appropriate file.
If due to a track view filter only a part of the data packets have been displayed, this
reduced view is displayed when opening a stored file first. In the background
however, the entire trace is present and can be represented by a change of the
trace view filter. Furthermore the last used settings for trigger and recording filter
are stored and can be used for the data analysis as well.
With the export of a *.tsv-file in Excel data formats are queried. The following set-
tings are recommendable: "separated" for the data type, "Tab stop" for separators,
" as text recognition characters and "text" as data format for all columns. If due to
a trace view filter only a part of the data packets have been displayed at the mo-
ment of storing this reduced view appears in Excel. The rest of the file cannot be
represented. However that solves another problem: Excel can represent only a li-
mited number of lines. Due to a view filter the trace can be reduced in such a way
that it is representable in Excel (In the last column the content of all lines is repea-
ted in a hexadecimal form for a second time).
Subject to reasonable modifications due to technical advances.
