Reference: Limit Line File Format
Limit line data can be exported to a file in ASCII (CSV) format for further evaluation in
other applications. Limit lines stored in the specified ASCII (CSV) format can also be
imported to the R&S
FSV/A for other measurements (see
on page 484). This reference describes in detail the format of the export/import files for
limit lines. Note that the
bold
data is
mandatory
, all other data is optional.
Different language versions of evaluation programs may require a different handling of
the decimal point. Thus, you can define the decimal separator to be used (see
Table 9-2: ASCII file format for limit line files
