FOOTNOTES
(1) Units with any of the following options: B40, DP2, MPB
(2) Units without any of the following options: B40, DP2, MPB
(3) The Tuning Equations below show the relationship between
the A14 LO Synthesizer output and the Tuned Frequency in SA mode.
Band Tuning Equation
0 - 3.6 GHz LO Synth Output = Tuned Freq + 5.1225 GHz
3.6 - 8.4 GHz LO Synth Output = Tuned Freq + 322.5 MHz
8.4 - 13.6 GHz
LO Synth Output = (Tuned Freq + 322.5 MHz)/2
13.6 - 17.1 GHz
LO Synth Output = (Tuned Freq + 322.5 MHz)/2
17.1 - 26.5 GHz
LO Synth Output = (Tuned Freq + 322.5 MHz)/4
