Measurement Description
DCD Duty cycle distortion. The peak-to-peak amplitude for the component of the deterministic jitter
correlated with the signal polarity.
The measurement is taken on the entire record.
DDJ Data dependent jitter. The peak-to-peak amplitude for the component of the deterministic jitter
correlated with the date pattern in the waveform.
The measurement is taken on the entire record.
DJ Deterministic jitter. The peak-to-peak amplitude of all timing errors that exhibit deterministic
behavior.
The measurement is taken across the entire record.
DJ-δδ Dual-Dirac deterministic jitter. The deterministic jitter on a simplifying assumption that the
histogram of all deterministic jitter can be modeled as a pair of equal-magnitude Dirac functions.
The measurement is taken on the entire record.
F/2 The peak-to-peak amplitude of the periodic jitter occurring at a rate of Fb (date rate) divided by
two.
The measurement is taken on the entire record.
F/4 The peak-to-peak amplitude of the periodic jitter occurring at a rate of Fb (date rate) divided by
four.
The measurement is taken across the entire record.
F/8 The peak-to-peak amplitude of the periodic jitter occurring at a rate of Fb (date rate) divided by
eight.
The measurement is taken on the entire record.
J2 The total jitter at a bit error rate of 2.5e-3 (TJ@2.5e-3).
The measurement is taken on the entire record.
J9 The total jitter at a bit error rate of 2.5e-3 (TJ@2.5e-3).
The measurement is taken on the entire record.
Jitter Summary Adds multiple jitter measurements to the measurement badge, and displays Bathtub, TIE
Spectrum trend plot, TIE Histogram, Eye Diagram plots on the screen.
NPJ Nonperiodic jitter. The portion of the BUJ (Bound uncorrelated jitter) that is random. BJU
excludes DDJ, DCD, and RJ.
The measurement is taken on the entire record.
Phase Noise The RMS magnitude of all integrated jitter falling within a specified offset range of the
fundamental clock frequency.
The measurement is taken on the entire record.
PJ Periodic jitter. The peak-to-peak amplitude of the uncorrelated sinusoidal components of the
deterministic jitter.
The measurement is taken on the entire record.
RJ Random jitter. The RMS magnitude of all random timing errors following a Gaussian distribution.
The measurement is taken on the entire record.
RJ-δδ Dual-Dirac random jitter. The random jitter on a simplifying assumption that the histogram of all
deterministic jitter can be modeled as a pair of equal-magnitude Dirac functions.
The measurement is taken on the entire record.
SRJ Sub-rate jitter. The composite jitter due to periodic components at ½, 1/4, and 1/8 of the data
rate.
The measurement is taken on the entire record.
