4. You may want to select a different number of samples in the range from 1 to 10,000 blocks; the default is 100.
5. In the RF Output Power entry field, select the power level at which you want to perform the receiver
measurement.
6. Push the Start Test soft key.
The measurements are started, and the menu is frequently updated with results.
’Interpreting the results’ on page87 explains how the results should be read.
Note
The BLER is performed over a single time slot, independent of the setting in the Slots input field. Each
measurement result is generated from a user-defined number of samples. A sample in case of the
BLER-BCS measurement is a block, which takes 20 ms to send. So if you select 200 samples, a
measurement result is returned every four seconds.
