Waveform Data
A waveform may have more than one data set. Each waveform data set
Header
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.

A 32-bit integer that identifies the unit of measure for X values in the acquired
data:
• 0 = Unknown.
• 1 = Volts.
• 2 = Seconds.
• 3 = Constant.
• 4 = Amps.
• 5 = dB.
• 6 = Hz.
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.
A 16-byte character array, left blank in InfiniiVision oscilloscopes.
A 16-byte character array, left blank in the InfiniiVision oscilloscopes.
A 24 byte character array that is the model number and serial number of the
oscilloscope in the format of: MODEL#:SERIAL#.
A 16 byte character array that contains the label assigned to the waveform.
A 64-bit double, only used when saving multiple segments (requires
segmented memory option). This is the time (in seconds) since the first
trigger.
A 32-bit unsigned integer. This is the segment number. Only used when saving
multiple segments.
A 32-bit integer that is the size of the waveform data header.
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).
