Jitter/Latency Results
Latency Statistics:
³
Current: Displays average of the measured delay values of the last
second.
³
Average: Displays average of the measured delay values from the
beginning of the test.
³
Minimum: Displays minimum measured delay value from the
beginning of the test.
³
Maximum: Displays maximum measured delay value from the
beginning of the test.
³
Threshold: When the Latency Pass/Fail Verdict is enabled, Threshold
value can be set in milliseconds. Latency Pass/Fail verdict is declared
as PASS when the maximum latency value is smaller than or equal to
the threshold. Latency Pass/Fail verdict is declared as FAIL when the
maximum latency value is greater than the threshold.
Note: Delay variation measurements smaller than 15 us are discarded.
Note: Only the round-trip latency can be measured (loopback testing topology).
