All trace files have the file name extension *.TRC as a default setting, that is, if the file
name only is specified, without an extension, this extension is automatically added.
Other extensions are allowed. Clicking on the … button opens the file selector with all
known properties.
During the loading procedure, the system tests whether the trace file can be loaded.
When trace files are stored an identifier is entered so that it is obvious from which
graphic system the file was saved. Trace files can only be loaded into the graphic sys-
tem from which they were saved; in all other cases the attempt to load is ignored and
an error message is issued. Exception: When Bar Graph trace files are being loaded,
the system recognizes from the number of stored lines whether the file matches the set
measurement function. For example, a Bar Graph trace file with 9 frequency lines in a
bar graph display would be rejected for the measurement function DFD, because only
5 lines are expected there.
However, if there is ever a need to load a trace file of a different type into a graphic
system, acceptance of the file can be forced through by changing the trace file identi-
fier in an ASCII editor; see section
Chapter 5.55, "Editing" , on page 621.
If a trace file cannot be loaded, or if "Y-Source " = File: Trace A or File: Trace B
addresses a trace file in which the required trace does not exist, an appropriate warn-
ing is issued and the loading procedure is terminated. The previous trace in the graphi-
cal display remains unchanged.
The content of the trace files defines the appearance of the DispConfig panel and the
associated display panel.
The appropriate scan is loaded from the trace file, depending whether "Scan " = Single
or Multi in the parameter field and whether "Show
Min Max " is set.
The following figure shows the parameter fields and wordings which are influenced by
the file content.
