If the V
cc,min
value is changed (V
cc,min
> 0 V), then the following applies:
●
If 0 < V
in
/V
in,max
≤
V
cc,min
, the signal is clipped and V
cc
Norm = V
cc,min
●
If V
in
/V
in,max
> V
cc,min
, then V
cc
Norm = V
in
/V
in,max
For the previous example, if V
cc,min
= 200 mV, that V
cc
Norm = V
cc,min
= 0.2 V.
Example: Calculating the current V
CC
in "Manual" mode
In "Envelope Voltage Adaptation > Manual" mode, set the parameter "Pre-Gain = PEP
= - 3.4 dB".
The displayed shaping function resembles the shaping function in "Auto Normalized"
mode; the same formulas apply, too.
You can also query the V
CC
values for any specified x in the supported voltage adapta-
tion mode and units.

Additional information
The described principle applies for any shaping function.
