Remote command:
EXPort:WAVeform:SOURce on page 349
Points
Selects the number of data points to be saved in the waveform file.
●
"Display Data": Saves all currently displayed waveform samples.
●
"Acq. Memory": Saves all data samples that are stored in the acquisition memory.
This setting takes effect only for stopped acquisitions. For running acquisitions,
only always display data can be saved.
●
"History Data": Saves the waveform data of the history segments.

Remote command:
CHANnel<m>:DATA:POINts on page 341
Save
Saves the data to the selected storage directory. The used path and file name are dis-
played when the storage is completed.
Saving is not possible if "Points" is set to "Acq. Memory" or "History Data" and the
acquisition is running.

9.2.2 Waveform File Formats
Data of all waveforms is saved as a succession of values or pairs of values. Pairs of
values are written as two consecutive single values. Depending on the file format, only
amplitude values are stored, or the amplitude values are stored together with their time
value, or frequency value in FFT mode.
With export/import, you can change the target file format and convert the data.
To reload waveform data as a reference waveform, it must be stored in TRF or CSV
format.
9.2.2.1 CSV Format
In a Comma Separated Values text file, the waveform is stored in a two-columned
table. Columns are separated by a comma, and the lines are separated by line breaks
\r\n (0x0D 0x0A). Values are listed in scientific notation.
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.
