 CH1 Skew / CH2 Skew / CH3 Skew / CH4 Skew
These numeric fields can be used to set-up the absolute delay for each
channel in seconds. The valid range for them is -100ps ... +100ps. This feature
may be used to control the skew of data and clock signals.
Jitter + SSC Tab:
This tab includes different sections to control a variety of the signal timing
characteristics, the injection of several jitter profiles and timing impairments. Each
timing control section can be enabled by checking the checkbox located at the top right
corner of each section. In order to edit the parameters in each section and to activate
their effects in the waveform being generated, the corresponding checkbox must be
checked.
SSC Section: Spread-Spectrum Clock characteristics are defined in this section. The
following controls are available:
 SSC Profile: Sine, Square, Triangular, and Sawtooth profiles are available. SSC
profiles are always symmetrical with respect to the nominal signaling rate.
 Dev(pkpk): The peak-to-peak symbol clock deviation is expressed in ppm
(parts per million) of the nominal (average) signaling rate .
 Rep. Rate: This is the repetition rate for the active SSC profile and is expressed
in in Hertz (Hz).
Sinusoidal Jitter Section: Up to ten components of sinusoidal jitter can be
independently set-up in this section. As amplitude, frequency and phase can be
individually defined for each component, more complex periodic patterns can be also
defined through their Fourier series development. The following controls are available:

Comp #: This combo box allows the selection of any of the ten components (1-
10) for edition. The rest of the controls in this section will be referred, then, to
