If a data set is subsequently edited manually, comment lines (which can be identified
by a
'#' at the beginning of the line ) can be inserted at any position ahead of the X/Y
pairs. A data set must never be interrupted by comments .
5.55 Editing
The editing of trace files, equalization files, sweep lists and limit files is always carried
out in the same way and is illustrated by two examples. The procedure is not explained
point by point in the examples – this would be beyond the scope of this description.
The examples are really intended for the trained user.
Example:
The intention is to generate a tolerance band from the frequency response of an ideal
DUT. This tolerance band will be compared to the other DUTs.
The measured value sequence of this ideal DUT is generated by means of a 30 point
sweep.
Using "Store Trace as " "Limit List", a limit file with 30 pairs of X/Y values is generated
from this measured value sequence and stored as LH_30_up.lim. The Y values of the
limit curve are provided with an additive offset of 10
dBV, producing a limit curve that
is parallel shifted by 10 dBV compared to the measured value sequence.
If the limit curve is loaded as Limit Upper, the parallel shift can be seen to be upward.
