Waveform Header
Each waveform in the file has a waveform header describing the waveform data.
Header Size
A 32-bit integer that is the number of bytes in the header.
Waveform Type
A 32-bit integer that is the type of waveform stored in the file: 0 = Unknown, 1 =
Normal.
Number of
Waveform Buffers
A 32-bit integer indicating the number of waveform buffers required to read the
data.
Points
A 32-bit integer that is the number of waveform points in the data.
(Reserved)
A 32-bit integer equal to 0. Reserved for future use.
X Display Range
A 32-bit floating point number that is the X-axis duration of the waveform that is
displayed. For time domain waveforms, it is the duration of time across the dis-
play. If the value is zero, no data has been acquired.
X Display Origin
A 64-bit, double-precision, floating-point number that is the X-axis value at the
left edge of the display. For time domain waveforms, it is the time at the start of
the display. If the value is zero, no data has been acquired.
X Increment
A 64-bit double that is the duration between data points on the X axis. For time
domain waveforms, this is the time between points. If the value is zero, no data
has been acquired.
X Origin
A 64-bit, double-precision, floating-point number that is the X-axis value of the
first data point in the data record. For time domain waveforms, it is the time of the
first point. If the value is zero, no data has been acquired.
X Units
A 32-bit integer that identifies the units for X values in the 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.
(Reserved)
A 16-byte character array. Reserved for future use.
(Reserved)
A 16-byte character array. Reserved for future use.
Frame
A 24-byte character array that is the instrument’s model number and serial num-
ber in the format: MODEL#:SERIAL#.
Waveform Label
A 16-byte character array that contains the label assigned to the waveform.
(Reserved)
A 64-bit double. Reserved for future use.
(Reserved)
A 32-bit unsigned integer. Reserved for future use.
