4.2.7 Measurement Results
The WCDMA TPC measurement provides all measurement results in a single view.
This view displays two diagrams, showing the measured UE power vs slot and the cor-
responding power steps between the slots. Configured limits are indicated by red limit
lines.
Below the diagrams, a table providing a statistical evaluation of the UE power vs slot
results is displayed. The contents of the table depend on the measurement mode and
on the selected TPC setup.
