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 Agilent Technologies web site at
www.agilent.com/find/7000sw.
Agilent 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.
Cookie Two byte characters, AG, that indicate the file is in the Agilent
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.
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.
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:
