X Units 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.
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.
