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.
