2.1.11 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 semico-
lon.
Exporting a single trace vs exporting all traces
Note that the file containing the trace data has a slightly different structure when you
export all traces compared to exporting a single trace only. The differences are indica-
ted in the tables below.

Description
Signal-to-noise and distortion
Measures the ratio of the total power to the power of noise and har-
monic distortions. The noise and harmonic power is calculated
inside the AF spectrum span. The DC offset is removed before the
calculation.

Total harmonic distortion
The ratio of the harmonics to the fundamental and harmonics. All
harmonics inside the AF spectrum span are considered up to the
tenth harmonic.
