Field Explanation
Linear: RF feedback sample is taken after high power filter.
Success/Attempt x/x The digit to the right of the / indicates the number of times that corrector
attempted to make a correction.
The digit to the left of the / indicates the number of times the corrector
succeeded in making a correction. Just because the number of attempts does not
equal the number of success does not mean that RTAC is not functioning.
Adapt Pressing the Adapt soft key turns it green and turns the selected corrector on.
The correction algorithm will continuously calculate and update correction as
needed. When switching to this mode from any other mode, the correction
algorithm is reset. Which will also reset the number of success and
attempts.The normal operational mode is Adapt.
Hold Pressing the Hold soft key turns it green and keeps the last correction value for
the selected mode. This is a short term option. For long term use select Stored.
With HOLD active correction is engaged but not adapting to any new solution
for changes in the amplifiers or filters.
Stored Pressing the Stored soft key turns it green and selects a previously stored set of
corrections which are used as a static digital precorrection. The corrections are
saved by using the Stored Correction Sets sub window in the RTAC Page 2
screen on right Figure 3-16 on page 3-24 and at Section 3.4.2.1. Storing the
current active RTAC filter setup or operating from a previously stored setup is covered in
Section 3.4.2.1.
