Jitter/Latency Results

Press , select Traffic Generation & Monitoring, Results, and the

Jitter/Latency tab.

Note: The Jitter/Latency parameters are calculated for the main stream only.

Jitter Statistics:

³ Current: Displays average

of the measured delay

variation values of the last

second for the main

stream.

³ Average: Displays average

of the measured delay

variation values from the

beginning of the test for

the main stream.

³ Minimum: Displays minimum measured delay variation value from

the beginning of the test for the main stream.

³ Maximum: Displays maximum measured delay variation value

from the beginning of the test for the main stream.

³ Estimate: Displays last jitter estimate value based on an

exponential filter of 1/16 for the main stream.

³ Threshold: When the Jitter Pass/Fail Verdict is enabled, Threshold

value can be set in milliseconds. Jitter Pass/Fail verdict is declared as

PASS when the maximum jitter value is smaller than or equal to the

threshold. Jitter Pass/Fail verdict is declared as FAIL when the

maximum jitter value is greater than the threshold.
