This screen presents the Throughput results in graph or table. Touch the
Graph and Table buttons to switch between the tabular form and a
graphical presentation of the results.
The ideal throughput, RTT and TCP Efficiency are shown in the graphical
presentation.

In bidirectional mode, the measured throughput in bidirectional mode is less
than the ideal in one way mode. This is due to the overhead caused by
interleaving returning ACK frames into the transfer. The ideal throughput of
the instrument in bidirectional mode is calculated by considering the
estimated interleaving returning ACK frame.
In case of connecting iPerf server, the "Interval" result of iPerf server is
displayed more 1 second than the "Actual Transfer Time" result of the
instrument. When you check the result of iPerf server, it is recommended to
set the duration of the test by sufficient long period.
