Y Units A 32-bit integer that identifies the unit of measure for Y values in the acquired
data. The possible values are listed above under “X Units”.
Date A 16-byte character array, left blank in InfiniiVision oscilloscopes.
Time A 16-byte character array, left blank in the InfiniiVision oscilloscopes.
Frame A 24 byte character array that is the model number and serial number of the
oscilloscope in the format of: MODEL#:SERIAL#.
Waveform Label A 16 byte character array that contains the label assigned to the
waveform.
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
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.
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.
