Jitter Tolerance Characterization - Reference
Jitter tolerance characterization determines the actual jitter levels where the
device under test can no longer maintain a desired BER.
Frequency Specification
You can choose Auto or Manual mode.
In Auto mode, the jitter frequency is automatically swept from Start Frequency to
Stop Frequency.
• Start Frequency: This is the minimum and first jitter frequency to be generated.
It determines the left-hand border of the graphical result display.
• Stop Frequency: This is the maximum and last jitter frequency to be generated.
It determines the right-hand border of the graphical result display.
The measurement always includes the start and stop frequencies. The
frequency scale is logarithmic.
• Number of Steps: The Number of Steps between start and stop defines the
test frequencies.
To determine the individual test frequencies, an algorithm divides the horizontal
logarithmic scale into a set of logarithmically equidistant frequencies.
