Set the jitter measurement item
⚫
The jitter measurement items supported by this oscilloscope include TIE, Cycle
to Cycle, +Width to +Width, and –Width to -Width.
Click Item to select the desired measurement item.
TIE
➢
Compares edges in a signal under test with the edges in an ideal signal
determined by the clock recovery feature. Then, all the signal intervals are
measured based on the ideal data rate to generate the error statistics.
Cycle to Cycle
➢
Measures the first cycle and then subtracts the first cycle from the second
cycle. The measurement is made according to this rule.
