R&S FSL Setting Traces – TRACE Key
1300.2519.12 4.51 E-11
ASCII file export format
The data of the file header consist of three columns, each separated by a semicolon: parameter name;
numeric value; basic unit. The data section starts with the keyword "Trace <n>" (<n> = number of
stored trace), followed by the measured data in one or several columns (depending on measurement)
which are also separated by a semicolon.

data section of the file
Description
Trace 1:;; Selected trace
x–Unit;Hz; Unit of x values: Hz with span > 0; s with span = 0; dBm/dB with statistics measurements
y–Unit;dBm; Unit of y values: dB*/V/A/W depending on the selected unit with y–axis LOG or % with y–
axis LIN
Values; 501; Number of measurement points
10000;–10.3;–15.7
10180;–11.5;–16.9
10360;–12.0;–17.4
...;...;
Measured values: <x value>, <y1>, <y2>; <y2> being available only with detector
AUTOPEAK and containing in this case the smallest of the two measured values for a
measurement point.
