Optional Linearizer D-1

Appendix D

Optional Linearizer

The optional Linearizer has been adjusted for optimum performance at the

factory. Tube replacement will require readjustment of the Linearizer at the

factory by trained personnel (see the service manual for more details).
The user may modify the linearizer settings from the factory values. Doing so

may cause the MPA Hub Mount performance to degrade. For this reason it is

recommended that if the user wants to change these settings, they should

always record the factory set values (below) before making any changes.

Linearizer Adjustment

Factory set value (0-255)

Gain

Phase

Magnitude

The Linearizer settings can be accessed via the optional CPI remote panel or

through the supplied “Setup & Remote control” Software (see Appendix B).
