Scale the X and/or Y Data


The scaling commands set parameters that are applied when you read the data; they have no effect if you read the data and then enter the scaling command. These parameters are reset by a DE command.

sets the scale factor and offset for the y data:   

			y-stored = (y-read * scale) + offset


Raw data is converted from a 12 bit value to 0-5 volts before it is scaled.

The data element name you have entered will appear in the prompt:

	Command[ ]? SH 55806			!shot number

Command[ ]? DE [GS]CCIG-GSS-PT1-S1 ; !torus pressure

Command[ ]? YC !set scale factor

CCIG-GSS-PT1-S1 Offset[0.]? ,

CCIG-GSS-PT1-S1 Multiplier[1.]? 2E-5

Command[ ]? R

Command[ ]? XV !fix up x axis

for curve[F1C1]? ,

X axis initial value[-6.]? -1. !start at -1 sec

Total number of values[8192]? ,

delta X[9.9999998E-03]? .01 !delta-t = .01 sec

points with this delta[8192]? , !all points

Command[ ]? P

sets the scale factor and offset for the x data. 

sets a hexadecimal mask that is applied to the data when it is read. This is useful for some raw data where high order bits are spuriously set in the digitizers.
