(3) The Tuning Equations below show the relationship between
the A14 LO Synthesizer output and the Tuned Frequency in SA mode.
0 - 3.6 GHz LO Synth Output = Tuned Freq + 5.1225 GHz
LO Synth Output = Tuned Freq + 322.5 MHz
LO Synth Output = (Tuned Freq + 322.5 MHz)/2
LO Synth Output = (Tuned Freq + 322.5 MHz)/2
LO Synth Output = (Tuned Freq + 322.5 MHz)/4
