The query returns 10 waveform parameters separated by ",":   
<format>,<type>,<points>,<count>,<xincrement>,<xorigin>,<xreference>,<yincrem
ent>,<yorigin>,<yreference> 
 
Wherein, 
<format>: 0 (BYTE), 1 (WORD) or 2 (ASC).   
<type>: 0 (NORMal), 1 (MAXimum) or 2 (RAW).   
<points>: an integer between 1 and 24000000. 
<count>: the number of averages in the average sample mode and 1 in other modes.   
<xincrement>: the time difference between two neighboring points in the X direction.   
<xorigin>: the start time of the waveform data in the X direction.   
<xreference>: the reference time of the data point in the X direction.   
<yincrement>: the waveform increment in the Y direction.   
<yorigin>: the vertical offset relative to the "Vertical Reference Position" in the Y 
direction.   
<yreference>: the vertical reference position in the Y direction.
