* TYPE : int16-0=NORMAL, 1 = PEAK DETECT,
* 2 = AVERAGE.
* POINTS : int32 - number of data points transferred.
* COUNT : int32-1andisalways 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.
