Combined RF Upconverter/Downconverter to the default state settings. There are 5 re-writeable mem-
ory locations, specified by choosing an index between 1 and 5. The parameters restored are the
RF
Power State, Upconverter LNA Power State, Reference Frequency, External Reference Enable, External
Reference Switch Override, Tune Frequency, External LO1 Enable, External LO1 Switch Override, LO1
PLL Mode, LO1 Reference Divider, External LO2 Enable, External LO2 Switch Override, Upconverter
