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 154).

Frame Loss: See QoS Metrics on page 197.

Out-Of-Sequence: See QoS Metrics on page 197.

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 154).
