Streams - Frame Loss / Out-of-Sequence
Streams - Frame Loss / Out-of-Sequence
From the Test menu, tap Results, Streams, and the Frame Loss /
Out-Of-Sequence tab.
Stream: Indicates the stream identification number.
Thresholds button allows to set the pass/fail thresholds (refer to QoS
Metrics on page 227).
Frame Loss: See QoS Metrics on page 275.
Out-Of-Sequence: See QoS Metrics on page 275.
Streams - Jitter
From the Test menu, tap Results, Streams, and the Jitter tab.
Stream: Indicates the stream identification number.
Jitter (ms) is measured for each stream on all valid frames
(in-sequence frames, valid Jitter tag, and no FCS error) received.
Current, Average, Minimum, Maximum, and Estimate delay values
are reported.
Note: Delay variation measurements smaller than 15 μs will be discarded, not
used for the sampling process, and “< 0.015” will be displayed as the
minimum value. For the Current value, Not measurable is displayed when
no delay has been measured in the last second.
Thresholds button allows to set the pass/fail thresholds (refer to QoS
Metrics on page 227).
