Reference
Number of
Waveform
Buffers
An integer (4 byte signed) which is the number of waveform buffers
required to read the data. This value is one except for peak detect data
and digital data.
Count
An integer (4 byte signed) which is the number of hits at each time bucket
in the waveform record when the waveform was created using an
acquisition mode like averaging. For example, when averaging, a count of
four would mean every waveform data point in the waveform record has
been averaged at least four times. The default value is 0.
X Display Range A float (4 bytes) which is the X- axis duration of the waveform that is
displayed. For time domain waveforms, it is the duration of time across
the display. If the value is zero then no data has been acquired.
X Display Origin
A double (8 bytes) which 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. This value is treated as a double precision 64- bit floating point
number. If the value is zero then no data has been acquired.
X Increment
A double (8 bytes) which 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 then no data has been acquired.
X Origin A double (8 bytes) which 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.
This value is treated as a double precision 64- bit floating point number. If
the value is zero then no data has been acquired.
X Units An integer (4 byte signed) which is the number of X units columns (n)
depends on the number of sources being stored. The X units is the unit of
measure for each time value of the acquired data. X unit definitions are:
0 = Unkown
1 = Volt
2 = Second
3 = Constant
4 = Amp
5 = Decibel
Y Units
An integer (4 byte signed) which is the number of Y units columns (n)
depends on the number of sources being stored. The Y units is the unit of
measure of each voltage value of the acquired waveform. Y units
definitions are:
0 = Unkown
1 = Volt
2 = Second
