Round Trip Latency
The round trip 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 round
trip latency. For Dual Test Set, the Round Trip Latency is only displayed on
the Remote to Local page.
Note: Delay measurements smaller than 15 μs 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.
