Delay Variation
10 Gigabit Ethernet Analyzer 87
The screen displays two columns. The first one contains the limits of
subintervals, the second one contains the number of packets (in
percentage terms) for which the jitter/latency belongs to the specified
subinterval. The upper interval limit can be set in the Delay Variation >
Setup menu. It is specified as Jitter/Latency Threshold, ms. The interval
from zero to the set threshold is divided into a certain number of
subintervals. According to the results of the test, the percentage of packets
for which the jitter/latency lies within these limits is displayed for each
subinterval in the right column.
To open the screen which contains the graphical representation of the
packet jitter/latency, press
(Plot).
Press (Save/Load) to open the menu which allows displaying
information about saved measurements ( ), saving test results and
