The maximum peak-to-peak Amplitude is limited by the chosen frequency.
The maximum Frequency of the rSSC jitter source depends on the amplitude.
Sinusoidal Jitter Parameters
Sinusoidal jitter (SJ) is independent from periodic jitter. It is generated by
modulating the clock that is used for data generation. It can therefore not be
enabled, if SSC or rSSC is active.
Sinusoidal jitter is characterized by
• Amplitude (peak-to-peak)
• Frequency
There is a dependency between frequency and acceptable amplitude. A graph
indicates whether the chosen setting of frequency and amplitude is acceptable.
The maximum peak-to-peak Amplitude is limited by the chosen jitter frequency.
Note that high-frequency sinusoidal data jitter can be generated by the Periodic
Jitter function or by applying an External jitter source.
