Si 5310- EV B
Spectrum Analyzer
A spectrum analyzer measures the power of the carrier
source and its associated phase noise. Analysis of the
offset power distribution provides the data from which
jitter can be derived. Simple integration of the offset
power distribution over the desired offset range and
filtered amplitudes provides a RMS jitter value.
Phase-noise Analyzer
A phase-noise analyzer behaves similarly to a spectrum
analyzer, but only provides details regarding the power
offset from the carrier. Simple integration of the offset
power distribution over the desired offset range and
filtered amplitudes provides a RMS jitter value.

Jitter Transfer
Jitter transfer is the ratio of the input jitter spectrum to
the output jitter spectrum. Comparing the power levels
from the input jitter spectrum with the output jitter
spectrum provides the jitter transfer details. To
characterize this parameter, a modulation source is
added to the synthesizer. The FM modulation frequency
is the jitter frequency, and its relative amplitude on the
output
transferred. In Figure 2, position A should be used when
measuring this parameter.
