Figure 5.85. Packet jitter. Distribution

At the screen two columns are shown. In the first one, intervals are dis-

played, the second one shows the quantity of packets (percentage) jitter value
of which lies within corresponding interval.

Upper limit of an interval can be specified in the

Packet jitter. Setup

(see

Threshold, ms

parameter). Interval between null and the threshold value

is divided into defined number of sub-intervals. As a result of the test, in
the right column the percentage of packets with jitter within corresponding
sub-interval limits is displayed.
