04 | Keysight | M9068A Phase Noise X-Series Measurement Application - Technical Overview
Spot frequency phase noise
After a particular frequency offset has been identified for further
analysis, the spot frequency measurement provides the time
domain behavior of phase noise at that particular offset
(Figure 4).
The spot frequency measurement can be used to:
–– Monitor phase noise fluctuation versus time at a user-
specified single offset frequency
–– Take advantage of improved carrier frequency tracking range
with faster signal tracking
–– View graphic and numeric list formats
–– Find the signal from the full range of frequency with the
Auto Tune feature
The spot frequency signal tracking feature provides:
–– A simultaneous view of phase noise and delta frequency in
time domain
–– SSB, average SSB, carrier power, carrier frequency, carrier
frequency (initial), and carrier frequency delta in a table
