For more details on how to measure the phase noise of a
signal, refer to “Measuring Phase Noise” on page 55.
Marker Trace
Auto 1 2 3 4
Places a marker on the selected trace, if no markers have
been previously 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 will search 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. After enabling
this softkey, the 1st LO Loop filter bandwidth
will be changed from approx. 5 kHz 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 accuracy far away
from the carrier. When testing phase noise far away from the carrier,
select Optimize Phase noise (Off).
