Waveform Data
Header
A waveform may have more than one data set. Each waveform data set will have a
waveform data header. The waveform data header consists of information about
the waveform data set. This header is stored immediately before the data set.
Example Program for Reading Binary Data
To find an example program for reading binary data, direct your web browser to
www.keysight.com/find/3000X-Series-examples , and select "Example Program
for Reading Binary Data".
Examples of Binary Files
Single Acquisition
Multiple Analog
Channels
The following picture shows a binary file of a single acquisition with multiple
analog channels.
Time Tags A 64-bit double, only used when saving multiple segments (requires segmented
memory option). This is the time (in seconds) since the first trigger.
Segment Index A 32-bit unsigned integer. This is the segment number. Only used when saving
multiple segments.
Waveform Data
Header Size
A 32-bit integer that is the size of the waveform data header.
Buffer Type A 16-bit short that is the type of waveform data stored in the file:
• 0 = Unknown data.
• 1 = Normal 32-bit float data.
• 2 = Maximum float data.
• 3 = Minimum float data.
• 4 = Not used in InfiniiVision oscilloscopes.
• 5 = Not used in InfiniiVision oscilloscopes.
• 6 = Digital unsigned 8-bit char data (for digital channels).
Bytes Per Point A 16-bit short that is the number of bytes per data point.
Buffer Size A 32-bit integer that is the size of the buffer required to hold the data points.
