Type Type describes how the waveform was acquired: normal, raw,
interpolate, average, or versus. When this field is read back into the
oscilloscopes, all the modes, except versus, are converted to raw. The
default value is raw.
Points Points indicates the number of data points contained in the
waveform record. The number of points is set by the Record length
softkey in the Acquisition menu. The default value is 1.
Count Count represents the minimum number hits at each time bucket
in the waveform record when the waveform was created using an
ensemble 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. Count is ignored
when it is read back into the oscilloscope. The default value is 0.
XInc X increment is the time duration between data points on the
X-axis. X increment is equal to the YData range value for versus
waveforms. The default value is 2.441000000000000E-005.
XOrg X origin is the x-value of the first data point in the data record. X
origin is equal to the YData center value for versus waveforms. The
default value is −5.00000000000000E-002
XRef X reference is always set to zero when it is read back into the
oscilloscope. The default value is 0.
YData range Y data range is the full voltage range covered by the A/D
converter. If this field is omitted, it is calculated when read back into the
oscilloscope. The default value is 0.
YData center YData center is voltage level at the center of the YData
range. If this field is omitted, it is calculated when read back into the
oscilloscope. The default value is 0.
Coupling Coupling is ignored when it is read back into the
oscilloscope. The default value is dc 50 Ω.
XRange XRange is the time duration across 10 horizontal divisions of
the display. The default value is 1.00000E-001.
XOffset XOffset is the time at the left edge of the display. The default
value is −5.00000000000000E-002.
