DCD Duty Cycle
Distortion
UI Yes The DCD parameter models two types of jitter:
Positive pulse width jitter (PPWJ) and Clock DCD.
The PPWJ shortens or lengthens the logic 1
waveform. The Clock DCD emulates distorted clock
waveform effects on the transmitter output
waveform. You can select the DCD generation
method in the Transmitter Jitter/Noise Options
Window. The default DCD method is PPWJ –
(shortened positive waveform).
BUJ Bounded
Uncorrelated
Jitter
UI Yes Same as Deterministic Jitter. The default BUJ
method is Uniform distribution.
RJ Random Jitter UI-RMS or ps-
RMS
Yes RJ is assumed to be Gaussian. RJ can be specified in
either pico-second (ps-RMS) or UI-RMS.
SJ Sinusoidal
Jitter
Amplitude: UI
Frequency:
MHz
Yes Sinusoidal jitter can be specified with amplitude and
frequency.
DN Deterministic
Noise
mV Yes DN can be generated using a uniform distribution,
dual-Dirac, or truncated Gaussian method. You can
select the DN generation method in the
Transmitter Jitter/Noise Options Window. The
default DN method is uniform.
BUN Bound
Uncorrelated
Noise
mV Yes Same as DN. The default method is Truncated
Gaussian method with a Peak-to-RMS ratio of 14.
You can select the BUN generation method and
parameters in the Transmitter Jitter/Noise
Options Window.
RN Random Noise mV-RMS Yes RN is assumed to be Gaussian.
