Reference
If more than one source is on, all displayed sources will be saved, except math
functions.
When using segmented memory, each segment is treated as a separate
waveform. All segments for a channel are saved, then all segments of the next
(higher numbered) channel are saved. This continues until all displayed channels
are saved.
When the oscilloscope is in the Peak Detect acquisition mode, the minimum and
maximum value waveform data points are saved to the file in separate waveform
buffers. The minimum value data points are saved first; then, the maximum value
data points are saved.
BIN data - using
segmented
memory
When saving all segments, each segment has its own waveform header (see
"Binary Header Format" on page 333).
In BIN file format, data are presented as follows:
• Channel 1 data (all segments)
• Channel 2 data (all segments)
• Channel 3 data (all segments)
• Channel 4 data (all segments)
• Digital channel data (all segments)
• Math waveform data (all segments)
When not saving all segments, the number of waveforms is equivalent to the
number of active channels (including math and digital channels, with up to seven
waveforms for each digital pod). When saving all segments, the number of
waveforms is equal to the number of active channels multiplied by the number of
segments acquired.
Binary Data in MATLAB
Binary data from an InfiniiVision oscilloscope can be imported to The MathWorks
MATLAB®. You can download the appropriate MATLAB functions from the
Keysight Technologies web site at
www.keysight.com/find/3000X-Series-examples .
Keysight provides the .m files, which need to be copied into the work directory for
MATLAB. The default work directory is C:\MATLAB7\work.
