310 Keysight InfiniiVision HD3-Series Oscilloscopes User's Guide
24 Reference
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/HD3-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.
Binary Header Format
File Header There is only one file header in a binary file. The file header consists of the
following information.
Waveform Header It is possible to store more than one waveform in the file, and each waveform
stored will have a waveform header. When using segmented memory, each
segment is treated as a separate waveform. The waveform header contains
information about the type of waveform data that is stored following the waveform
data header.
Cookie Two byte characters, AG, that indicate the file is in the Keysight Binary Data file
format.
Version Two bytes that represent the file version.
File Size A 32-bit integer that is the number of bytes that are in the file.
Number of
Waveforms
A 32-bit integer that is the number of waveforms that are stored in the file.
Header Size A 32-bit integer that is the number of bytes in the header.
Waveform Type A 32-bit integer that is the type of waveform stored in the file:
• 0 = Unknown.
• 1 = Normal.
• 2 = Peak Detect.
• 3 = Average.
• 4 = Not used in InfiniiVision oscilloscopes.
• 5 = Not used in InfiniiVision oscilloscopes.
• 6 = Logic.
Number of
Waveform
Buffers
A 32-bit integer that is the number of waveform buffers required to read the
data.
Points A 32-bit integer that is the number of waveform points in the data.
