Source
Select the channels to be saved: either one active channel, or all active channels
together.
Remote command:
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:
Save
Saves the data to the selected storage directory. The used path and filename 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.

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.
To reload waveform data as a reference waveform, it must be stored in format TRF
(save reference) or CSV (save waveform).
10.2.2.1
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.
