Shaping Function in Raw Data Format
The shaping values are defined directly, with a single remote control command. You
define the up to 4000 comma-separated value pairs, describing the
Vin/Vmax,Vcc/Vmax
or
Power[dBm],Vcc[V]
.
Example:
SOURce1:OUTPut:ANALog:ENVelope:SHAPing:PV:FILE:DATA 0,0, 0.1,0.2, 1,1

Converting Shaping Functions and Understanding the Displayed Values
If an envelope function is defined, the "Shaping" dialog displays the diagram of the
resulting envelope shape (see for example
Several parameters influence the displayed information:
●
The selected "Envelope Voltage Adaptation" determines whether the x-axis uses
normalized or linear values
●
The selected "Graphic Configuration > Scale" sets the x-axis units
●
The selected V
cc
Min/Max and PEP
in
Min/Max values set the borders of the clipping
areas
●
The selected "Shaping" function and the parameters influence the envelope shape.
The illustration on
shows how these parameters influence a linear shaping
function.
