F/2 measurement algorithm
F/2 is the peak-to-peak amplitude of the periodic jitter occurring at a rate of Fb (data rate) divided by 2. This measurement is
made across the entire record.
F/4 measurement algorithm
F/4 is the peak-to-peak amplitude of the periodic jitter occurring at a rate of Fb (data rate) divided by 4. This measurement is
made across the entire record.
F/8 measurement algorithm
F/8 is the peak-to-peak amplitude of the periodic jitter occurring at a rate of Fb (data rate) divided by 8. This measurement is
made across the entire record.
J2
J2 is Total Jitter at a Bit Error Rate (BER) value of 2.5E-3. This statistical value predicts a peak-to-peak jitter that will only be
exceeded with a probability equal to the BER.
J9
J9 is Total Jitter at a Bit Error Rate (BER) value of 2.5E-10. This statistical value predicts a peak-to-peak jitter that will only be
exceeded with a probability equal to the BER.
Jitter Summary measurement
The Jitter Summary measurement is a predefined set of jitter measurements displayed in a single badge. The measurements
include TIE, TJ@BER, Eye Width@BER, RJ-66, DJ-66, PJ, DDJ, and DCD. This measurement also adds Eye Diagram, TIE
Histogram, Tie Spectrum, and Bathtub plots to the screen.
NPJ
Non-Periodic Jitter (NPJ) is the dual-dirac magnitude of that portion of Bounded Uncorrelated Jitter (BUJ) that is not periodic.
Since it is not periodic and is not correlated with the data pattern, NPJ is frequently difficult to distinguish from (Gaussian) RJ.
This component of jitter is not analyzed by default, but you can enable it by switching the jitter analysis mode to Sp BUJ.
Since it typically requires high populations to distinguish, you may need to acquire multiple waveforms before jitter results are
available when Sp BUJ mode is enabled.
Phase noise
The Phase Noise measurement performs a jitter measurement, converts the result into the frequency domain, and reports the
rms jitter integrated between two specific frequencies selected by the user.
The phase noise measurement is defined only for clock signals. If the source waveform appears to be a data signal, a warning
message will be produced but the measurement will proceed.
A Phase Noise measurement is required in order to enable the Phase Noise plot.
