18.2.2 About noise
Noise describes the amplitude deviation of a data symbol at the sampling time respec-
tive to a corresponding reference level. These deviations or level errors (LE) are
caused by various sources.
The total noise is split into two main components: random noise (RN) and deterministic
noise (DN). DN consists of periodic noise (PN) and non-periodic components.
The advanced noise algorithm enables various selectable result plots of the activated
noise components in the results tab.
18.2.3 Configuring the advanced jitter
To perform an advanced jitter analysis:
1. Open the "Analysis" > "Advanced Jitter" menu.
2. In the "Signal" tab, set up the analyzed signal and reference signal.
3. In the "Advanced Settings" tab, configure the "Data dependent" settings .
4. If necessary, enable "Periodic"/"(Other) bounded uncorrelated".
5. In the "Result" tab, enable all general and component-specific results diagrams,
that you want to display.
6. In the "Result" tab, "Add/ remove components". A dialog opens, where you can
enable all required measurements.
7. Press "Enable" to view all selected measurement results and diagrams.
18.2.4 Signal settings
Access: App Cockpit> "Analysis" > "Advanced Jitter / Noise" > "Signal" tab
In the "Signal" tab, you can set up the signal you want to analyze and define the refer-
ence clock signal.
