ParametersParameters
Allows you to specify when the measurement is started.
ImmediateImmediate: Starts the measurement when you touch the StartStart button.
Start atStart at: Starts the measurement at the time specified in the Start atStart at field on
the right.
Stop functionStop function
Allows you to specify when the measurement ends. Select the relevant option
from the drop-down menu:
Manual stopManual stop: Stops the measurement immediately when you touch the StopStop
button.
Stop atStop at: Stops the measurement at the time specified in the Stop atStop at field on the
right.
DurationDuration: Performs the measurement for the duration of time specified on the
right.
Memory allocationMemory allocation
Allows you to specify how the measurement will be stored in the Network
Master's memory. Select the relevant option from the drop-down menu:
Use all storageUse all storage: When Network Master's memory became full of measured
data, the whole measurement is stopped.
ContinuousContinuous: When Network Master's memory became full of measured data,
the oldest records in that memory will be overwritten.
The Network Master's memory size (the file size of measurement results) is 64
Mbytes per one port. The result file size is less than 64 Mbytes because it is
compressed when saving to the file.
Estimate of test durationEstimate of test duration
Contains an estimation of the time (in days, hours, minutes and seconds)
before the whole memory will be filled out by the test. The estimated value is
dependent on the current interface and selections concerning this interface.
During an ongoing measurement, the estimate will be recalculated periodically,
meaning that the estimate will get better and better. The estimate can be seen
on the status line during a measurement.
