A4, A15, and A17 13.5 GHz Synthesizer Boards
On 2-ports models, the A17 13.5 GHz synthesizer board is optional and
included only with Option 224.
The A4, A15, and A17 13.5 GHz synthesizer boards use the 50 MHz reference
signal from the A14 frequency reference board to tune two VCO circuits: one
that sweeps from 2 GHz to 4 GHz and one that is set to a fixed CW frequency of
3.4 GHz.
