Graphical and Tabular jitter
results
When testing jitter, you can view results in a graphical or tabular format by
selecting the corresponding result categories in the Interface group.
Jitter Graph
The jitter graph is available when manually testing jitter, and when measuring
MTJ and Fast MTJ.
MTJ Graph and Table
The MTJ graph and table are available when measuring MTJ and Fast MTJ.
JTF Graph
The JTF graph is available when measuring JTF.
Signal results
The Signal results report the same results as the other E1 tests. See “Signal
results” on page 79.
Interface results
The Interface results report the same results as the other E1 tests. See “Inter-
face results” on page 80.
