Ref 1~4 Reference waveforms stored in the
internal memory, separate from W1 ~
W20. Reference waveforms (Ref 1 ~ 4)
can be displayed directly onto the
display with amplitude and frequency
information. Ref 1~4 are useful for
reference purposes. Other waveforms (
LSF and W1~20) must be recalled to
R1~4 before being displayed.

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 DSxxxx.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, LM Detail CSV and LM Fast CSV.
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. CSV data will only record 5000 points of 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. Fast
CSV will only record 5000 points of data. Data is
recorded as integers.
LM Detail CSV is similar to CSV but covers the
entire long-memory (See page 109 for information
on the record length). All points are recorded in
scientific notation for analog data.
LM Fast CSV is similar to Fast CSV but covers the
