An equalization list in ASCII format is generated from the current measured value
sequence, taking into account the settings made under "Trace ", "Norm Freq ", "Invert "
and "Modify Equ. ". The list is stored to a file, which can be loaded by selecting it in the
"Equalizer" line in the Generator Function panel.
An equalization file may contain up to 1024 X/Y pairs, because a generator sweep can
have a maximum of 1024 sweep points. If a measured value sequence contains more
than 1024 X/Y pairs, data will be compressed automatically such that only every 2nd,
4th, 8th X/Y pair and so forth is stored to the equalization file.
If an equalization list is generated from a multiscan display (including also the Min/Max
scans of a single-scan display), the Y values of the currently selected scan are taken to
generate the list.
If the file name is specified without an extension, the suggested file name extension
is .VEQ, but any desired extension can be specified.
For a detailed description of the storage format, see section Chapter 5.54.2, "Equaliza-
tion Files" , on page 617.
5.52.3 Sweep Lists
A Sweep List contains any desired sweep axis. Since the individual values of X are
extracted from a current measured value sequence, they are in ascending order. If the
file is then manually processed, the
separations of the sweep points can be freely
selected in order to place a greater number at places of particular interest without dras-
tically increasing the total number of sweep points. The sweep points must, however,
be specified in ascending or descending order – they must not change direction. The
sweep points are processed by the sweep system in the order in which they are listed.
There must be at least two different points in the list.
The file can contain a maximum of 1024 X values, because a generator sweep can
have a maximum of only 1024 sweep points. If a measured value sequence has more
than 1024 X/Y pairs, the data is compressed automatically by saving only every 2nd,
4th, 8th, etc. value for the sweep list.
If a sweep list is saved from a multiscan display (including the Min/Max scans in the
case of a single scan display), the currently selected scan plays no role, since the X
values are the same for all scans.
If the file name is specified without an extension, the suggested file name extension
is .SPL, but any desired extension can be specified.
For a detailed description of the storage format, see section Chapter 5.54.3, "Sweep
Lists" , on page 618.
