When altering the number of X/Y values it is important to make sure that the Datacount
entry is adapted accordingly. The identifier
UPV LIMIT FILE must not be changed. If
the tabulator (TAB) is used as a separator between various entries in a line, the file can
be processed in EXCEL without any problem. Other separators are also permissible,
e.g. ';', '|' or ' '.
If the new limit curve named
LH_9_up.lim
is then loaded as "Limit Upper", the result
of the modification can be assessed and further processing can be performed if neces-
sary.
A limit file for the lower limit of a tolerance band can be generated in much the same
way as the procedure for modifying a limit file for the upper limit of a tolerance band.
The two limit files together produce the desired tolerance band.
Example:
The intention is to create a sweep file from the trace data set of a waveform file. Leave
to one side the matter of whether this serves any purpose. The example is intended to
show that any trace file can be created by editing.
The X values in the waveform trace file are expressed in seconds. But the x-axis in the
sweep trace file needs to be displayed in Hz. The level values on the y-axis are to stay
unchanged.
The left column shows the original Waveform Trace file, the right table column the
Sweep Trace file that was generated through editing.
