Waveform Data
The waveform data can be used for detailed
analysis. It consists of the horizontal and vertical
data used by the waveform.
Spreadsheet File Format
Format
*.csv (Comma-separated values format, can be
opened in spreadsheet applications such as
Microsoft Excel).
CSV-formatted files can be stored in either a short-
memory format or a long-memory format: Detail
CSV, Fast CSV. The number of points that are
saved depends on the record length settings.
Detail CSV will record both the horizontal and
vertical sample points of the waveform. All the
points are recorded in scientific notation for analog
data.
Fast CSV will only record the vertical amplitude of
the sample points. Fast CSV also contains data that
enables the horizontal data points to be
reconstructed, such as trigger position, etc. Data is
recorded as integers.
Note, however, that only fast CSV can be recalled
to the internal memory. Detailed CSV cannot be
recalled.
