Delay Line Display
The delay line display shows red markers that indicate the consumption of delay
line capacity by the present jitter setup.
Colored bars indicate the consumption by the various jitter components.
The consumption is shown in UI (Unit Intervals) and is calculated from the present
data rate. Because the delay lines have a fixed time capacity, the scales change
when the bit rate is changed.
N O T E
•
The total consumption of the delay line in UI is indicated on top of the delay line
display.
•
The delay line display for SSC/SJ shows the usage of the modulator in percent.
Jitter Setup Area
The Jitter Setup area shows the present jitter composition.
To become active, jitter sources must be switched on (by enabling the
corresponding button) and must at least have an Amplitude greater than zero.
