Key Performance Indicators

Latency (ms) : The latency (delay) is measured for each stream on all
valid frames. The maximum, minimum, current, and average delay
values are reported. The pass
or fail verdict is also displayed for
the maximum latency.
Note: Delay measurements smaller than 15 μ s will be discarded, not used for the
sampling process, and “< 0.015” will be displayed. For the Current value,
Not measurable is displayed when no delay has been measured in the last
second.
Note: When the Dual Test Set mode is set to Local on page 41, the results are
presented independently for each direction: Local-to-Remote ( L->R ) and
Remote-to-Local ( R->L ). However, for Latency, only one Round-trip
Latency value is displayed.
Note:
For DTS EtherSAM , the results for the Remote-to-Local direction are
obtained at the end of each step.
