'
COUNT
: int32 - 1 and is always 1.
'
XINCREMENT : float64 - time difference between data
'
points.
'
XORIGIN
: float64 - always the first data point in
'
memory.
'
XREFERENCE : int32 - specifies the data point associated
'
with the x-origin.
'
YINCREMENT : float32 - voltage difference between data
'
points.
'
YORIGIN
: float32 - value of the voltage at center
'
screen.
'
YREFERENCE : int32 - data point where y-origin occurs.

' QUERY_WAVE_DATA - Outputs waveform records to the controller
' over the interface that is stored in a buffer previously
' specified with the ":WAVeform:SOURce" command.
' READ_WAVE_DATA - The wave data consists of two parts: the
' header, and the actual waveform data followed by a
' New Line (NL) character.
The query data has the following
' format:
