9.5 CSV settings
The R&S LCX enables you to record measurement readings and save the data in a file
for subsequent evaluation and validation. Recorded data consists of character strings
that list general metadata, as, e.g., date, device name, etc., the parameter names and
the acquired measurement values.
The standard *.csv file format the R&S LCX saves the data, allows you to use a
spreadsheet program application for numerical or graphical analysis and evaluation.
A *.csv file saves tabular data (numbers and text) in plain text. Each line of the file is
a data record and each record consists of one or more fields, separated by a field
delimiter. In the "CSV Settings" dialog, you can set the special characters to set the
delimiters.
9.5.1 Settings for CSV data
