06 | Keysight | Phase Noise X-Series Measurement Application N9068A & W9068A - Technical Overview
Monitor spectrum
In addition to the phase noise
measurements, you can verify the
quality of the signal of interest with-
out having to switch from the phase
noise mode to the spectrum analyzer
mode. The monitor spectrum mea-
surement provides a simple frequency
domain view for a quick signal check.
In addition, the abundant marker/
trace functions for the X-Series signal
analyzers and MXE EMI receiver help
better quantify the signal in frequen-
cy domain (Figure 3).
IQ waveform
The phase noise X-Series measure-
ment application employs IQ analysis,
which maintains both amplitude and
phase information of the signal under
test. The IQ waveform measurement
enables you to view the signal in time
domain without having to switch
modes between the phase noise and
the IQ analyzer. This can significantly
decrease your measurement time.

Advanced marker functions
for Log Plot trace
The Log Plot measurement provides
a wide range of advanced markers
and marker functions so that you can
analyze various aspects of the trace,
such as integrated noise, averaged
noise density, and residual FM across
the applied band marker span, as
well as multiple spurious-peak search
functions and absolute, octave slope,
and decade slope scale delta mark-
ers. See Figure 4 and the following
tables for more detail.
