RF Symmetry Adjustment
You can adjust RF symmetry values using the remote AUI (see Adjusting RF Symmetry - Using the Remote
AUI ) or the local front panel UI (see Adjusting RF Symmetry - Using the Front Panel UI ). If you change a
setting on the front panel UI, it will also be reflected on the remote AUI, and vice versa.
Adjusting RF Symmetry - Using the Remote AUI
The
RF Symmetry
page (see Figure 3.2.139 ) allows entering RF symmetry values for exciter A or B to
attempt to minimize second harmonic content when operating on each exciter. Values are factory set
and should not require adjustment.
