This procedure adjusts several correction constants that can improve the output
power level accuracy of the internal source. They are related to the power
level, power slope, power slope offset, and the ALC roll-off factors among
others.
1. If you just completed “Sampler Magnitude and Phase Correction Constants
(Test
53),”
continue this procedure with step 8.
