Jitter Tolerance Tests
Jitter Tolerance Tests - Concepts
N O T E
This chapter refers only to Serial BERT instruments on which the calibrated and
integrated jitter injection option J10 is installed.
A jitter tolerance measurement is used to determine the ability of a
device or system to maintain communication quality in the presence of
jitter. It comes in two varieties:
•
Jitter Tolerance Characterization determines the jitter levels where
the device under test can no longer maintain a desired bit error ratio
(BER).
•
Jitter Tolerance Compliance verifies that the device under test is
able to maintain a BER level at pre-defined jitter levels and jitter
frequencies, as defined by a standard.
The basic setup of a jitter tolerance test is illustrated below:
