Select the Delay Line
To select the delay line for (sinusoidal) periodic jitter 1 and 2 and BUJ, press
610ps button. The LED will turn green if the 610ps delay line is selected.
Note that sRJ can not be enabled if the 610ps delay line is selected.
The 610ps delay line cannot be used for bit rates above 3.37 GHz.
Specify the Jitter Components
In this section, an example of periodic jitter 1 is shown to specify the jitter
components.
To specify the jitter components:
1 Activate a jitter source (press the corresponding button).
2 Set the most commonly used parameter (typically Amplitude and Frequency)
directly.
3 Press Edit button to access all parameters of the corresponding jitter type.
This opens a window which allows you to set all parameters available for the
