3 Adjustments

Introduction

The adjustment attempts to correct the power reference level if the performance
test has failed. Power reference level is controlled by the coarse and fine settings
of a digital potentiometer. Adjustment of the coarse and fine settings can only be
carried out via remote commands. Adjustment can be carried out without having
to remove the outer covers from the DUT.
