signal, please refer to “Measuring Phase Noise” on page 53.
Maker Trace
Auto 1 2 3 4
Activates a marker on the trace if there are no markers
turned on. If a marker is currently active, press Marker Trace
until 1, 2, 3, or 4 is underlined: the active marker moves to
the selected trace.
Selecting Auto mode moves the marker to the automatically
selected trace. The trace selection is to look for the lowest
numbered trace in the following mode order: Clear-write,
Max-hold, Min-hold and View. If there are no traces in any of
these modes, it selects trace 1.

Optimize
Phase Noise
This softkey is valid only when span fall in the
range of 100 Hz and 100 kHz. Once enable this
softkey, 1st LO Loop filter bandwidth will be
changed from 5 kHz or so to 120- 150 kHz
automatically, which optimizes the phase noise
close in to the carrier.
Key access:
> Function > Phase Noise

NOTE
Optimize Phase noise (On) will worsen phase noise far away from the
carrier. If you pay more attention to phase noise far away from the carrier,
select Optimize Phase noise (Off).
