A12 Synthesizer Assembly Description
Purpose. The A12 synthesizer assembly phase locks the A18 YTO,
resulting in a very stable, low phase noise LO signal. The A12
synthesizer assembly consists of sub-assemblies A12A1 LO/Synthesizer
board and the A12A2 sample oscillator. It is possible to replace each
sub-assembly, or the entire A12 synthesizer.
