6.4.1.3 General Throughput Settings (Global Configuration)
# of Streams:

Total (%):
Sum of all stream rates in %.
Throughput General Setup
Page 2 features One Way Delay measurement and Service Disruption Test (SDT) measurement settings.
Delay Measurement Mode:
Enable/disable the round trip delay measurement. It should only be enabled when running the
test to a remote loopback.
RTD Unit Auto Scale:
ON/OFF
Histogram:
Enable / Disable
Sampling Period:
1sec, 10secs, 30secs, 1min, 10min, 30min, 1hr. Defines how often the RTD (round trip delay)
measurement is evaluated against the RTD threshold.
Threshold (Max RTD allowed):
Input the value in us, ms or sec. Defines the maximum allowed round trip delay value. If the
RTD value exceeds the threshold, an event is logged with corresponding time stamp.
Save Histogram:
Enable/Disable
SDT Measurement
: Enable/Disable. The Service Disruption Test is triggered based on user established thresholds.
SDT Violation Threshold (us)
: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.
SDT Measurement Trigger (>us)
: 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.
