Reference
• 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 Agilent Technologies web site at
"www.agilent.com/find/2000X- Series- examples" .
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.
