Example Code
' GET_PREAMBLE - The preamble block contains all of the current
' WAVEFORM settings. It is returned in the form <preamble_block><NL>
' where <preamble_block> is:
' FORMAT : int16-0=BYTE, 1 = WORD, 4 = ASCII.
' TYPE : int16-0=NORMAL, 1 = PEAK DETECT, 2 = AVERAGE
' POINTS : int32 - number of data points transferred.
' COUNT : int32-1andisalways1.
' XINCREMENT : float64 - time difference between data points.
' XORIGIN : float64 - always the first data point in memory.
' XREFERENCE : int32 - specifies the data point associated with
' x-origin.
' YINCREMENT : float32 - voltage diff between data points.
' YORIGIN : float32 - value is the voltage at center screen.
' YREFERENCE : int32 - specifies the data point where y-origin
' occurs.
