Instruction Manual, Rev. 2 54
Item Selection
NLP Method Legacy, RLS, Regression
Used to select Pre-correction algorithm.
NLP Cycles Range: 1 .. 10
Ratio of NLP cycles to LP cycles. “X” number of NLP
cycles will run before one LP cycle is run.
Precorrection Stop, Run
Used to Run or Stop the cycles (adaptation processes).
Note: Pre-correction is not disabled when the cycles are
stopped.
Reset Precorector OFF, ON
Used to clear the NLP and LP coefficients.
Bypass To Host OFF, ON
Parameter is only set to ON if the Digital Pre-corrector is
controlled using the PC GUI application.

Table 14: Digital Precorrector Parameters
Note: If the user would like to use the Adaptive Pre-corrector PC GUI, several
parameters must be configured via the Web GUI (or CLI) before communication between
the modulator and Adaptive Pre-corrector GUI can be established. The user must set
the “Bypass To Host” parameter to “ON” and the “Precorrection” parameter to “Stop”.
