Performance
Parameters
Allows you to specify when the measurement is started.
Immediate: Starts the measurement when you touch the Start button.
Start at: Starts the measurement at the time specified in the Start at
field on the right.
Stop function
Allows you to specify when the measurement ends. Select the relevant
option from the drop-down menu:
Manual stop: Stops the measurement immediately when you touch the
Stop button.
Stop at: Stops the measurement at the time specified in the Stop at
field on the right.
Duration: Performs the measurement for the duration of time specified
on the right.
Memory 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 storage: When Network Master's memory becames full of
measured data, the whole measurement is stopped.
Continuous: When Network Master's memory becames 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.
Estimate 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. During an ongoing
measurement, the estimate will be recalculated periodically.
