The first column contains the time values of the samples in relation to the trigger point,
and the second column contains the associated amplitude values. The first line indi-
cates the units of the values in each column, and the name of the waveform. Pairs of
values are listed as two single values with the same time value (minimum and maxi-
mum).
The data can be loaded back to the instrument for further use.
Example CSV1:
Waveform of channel 1, single values

-1.1988E-02,1.000E-02
-1.1984E-02,1.000E-02
Example CSV2:
Waveform of channel 1, pairs of values

Import of CSV files:
If you import a CSV file as reference waveform from a USB flash
drive to the instrument, the import converts the data to TRF format. The instrument
reads the first and the last time value and calculates the total time of the waveform,
and it counts the number of values. Then all amplitude values are read one by one and
written with an equidistant time distribution to the TRF file. If the first two time values
are identical, the waveform is considered to consist of pairs of values.

TXT format
TXT files are ASCII files that contain only amplitude values but no time values. Ampli-
tude values are separated by commas. Pairs of values are listed as two subsequent
single values, without any identification. Amplitude values are given in scientific nota-
tion. There is no comma at the end of the file.
Amplitude values are given in scientific notation.
Example:

1.000E-02,1.000E-02,1.000E-02,1.000E-02,3.000E-02
