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:
• 0 = Unknown.
• 1 = Normal.
• 2 = Peak Detect.
• 3 = Average.
• 4 = Not used in InfiniiVision oscilloscopes.
• 5 = Not used in InfiniiVision oscilloscopes.
• 6 = Logic.
