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

parameters ( ), loading ( ) and deleting ( ) saved measurement

results and parameters (refer Saving test results and statistics on page 101).
