When this checkbox is disabled, no jitter is generated. This refers to the
whole composition shown on the screen. When this checkbox is enabled,
the present status becomes active.
N O T E
The Enable checkbox has no impact on SSC. If spread spectrum clocking is enabled
(from the Bit Rate Setup window of the Pattern Generator, see
), it continues, even if the Jitter Enable checkbox is off.
Delay Line Switch
This switch can be pressed to switch the source of periodic jitter to
either the 500
+
ps or the 200
+
ps delay line.
N O T E
The 500
+
ps delay line cannot be used for data rates above 3.37 GHz.
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.
Jitter Composition Overview
This section of the
Jitter Setup
function shows the present jitter
composition.
