Jitter/Latency Results
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.
