The allowed value for the maximum output power of the UE and the associated
tolerance values are defined according to its power class. Thus the measurement
results have to be in accordance with the following specifications:
Inner Loop test Select the [Inner Loop] marker tab to display the Inner Loop menu.
Function
Inner loop power control takes place between the UE and Node B 1500 times per
second (corresponding to the time slot length of 667 μs). Inner loop power
control requires accurate measurement of the level changes in the final test or
incoming inspection. This measurement verifies that the step is within the limits
(right size) and was performed at the correct time. On the Inner Loop Menu
20 steps of the inner loop power control can be displayed, in remote mode it is
possible to do even more. Furthermore the menu provides a Passed or Failed test
verdict.
