RTD Measurement:
Enable or Disable Round Trip Delay Measurement
SDT Measurement Trigger (>µs)
: Any inter-frame gap that is equivalent or greater than the configured threshold will trigger
the SDT measurement. This is useful if a known threshold is expected from a given network under test. For example, if the
known switchover time is 50ms, the trigger can be set to a value slightly below 50ms to assure that the SDT is measured.
SDT Violation Threshold (µs)
: Triggers an SDT Violation event in the event log. This is helpful for historical purposes during
any given test. If the measured SDT is equivalent or greater than the configured threshold an SDT Violation event is counted.
