Test Duration
This is the length of one measurement for detecting losses.
Number of Trials
The number of times that the AQ1300/AQ1301 will perform the series of operations from the start
of measurement to the point where the rate converges to the specified value. In one trial, frame
signals of the preset frame lengths are used to perform the loss detection measurements. The
throughput is the average of the values from all the trials.
Initial Rate
The traffic rate that is used when the throughput measurement starts.
Minimum Rate
This is the lower limit for the rate. The rate is decreased automatically whenever a loss is detected.
This is the minimum traffic rate that is used to converge the throughput measurement.
Maximum Rate
This is the upper limit for the rate. The rate is increased automatically when no losses are detected.
This is the maximum traffic rate that is used to converge the throughput measurement.
Resolution
This is the range that is used to converge the throughput measurement. When the difference
between the rates when a loss was detected and when no losses were detected falls within the
resolution range, the AQ1300/AQ1301 concludes the throughput measurement.
Acceptable Loss
This threshold value specifies the percentage of a frame signal that can be lost without a loss being
detected.
Pass/Fail Judgment
You can perform pass/fail judgments by setting the throughput threshold on the AQ1300/AQ1301 in
advance. If the value falls below the threshold, a fail judgment occurs.
Latency Measurement
In the latency measurement, the AQ1300/AQ1301 measures the delay when a network device
transmits frame signals. In this measurement, a fixed number of frame signals are transmitted (at the
test rate) over the specified measurement time (the test duration). These frame signals are looped
back by the other device. The delay of the intermediate frame signal from the fixed number of frame
signals is measured.
