Selects optimization for best wide offset phase noise
Parameter:
1. 1 optimizes phase noise for small frequency offsets from the carrier.
2. 2 optimizes phase noise for wide frequency offsets from the carrier.
3. 3 optimizes LO for tuning speed
(In PXA, the local oscillator hardware provides for extra-low phase noise at
the expense of some speed)
Does not appear in all models. The key is blank in those models, but the
SCPI command is accepted for compatibility (although no action is taken).
Because this function is in Auto after preset, and because Span after preset >
400 kHz (see Auto rules, next section) the state of this function after Preset
will be 2
