4.2.2 How to Perform a Measurement
In addition to the TPC measurement and the UE you need an application able to send
TPC commands to the UE.
It is recommended to use the WCDMA signaling application for this purpose (option
R&S CMW-KS400). The signaling application is compatible with all TPC measurement
modes.
In "Monitor" mode and "Inner Loop Power Control" mode you can alternatively use the
WCDMA generator (option R&S CMW-KG400) or a suitable waveform file together
with the GPRF generator (option R&S CMW-KW400 required to use WCDMA R99
waveform files generated via R&S WinIQSIM2).
General measurement procedure
The steps to be performed in detail depend on the application used to send the TPC
commands to the UE. The general procedure is as follows:
1. Connect your WCDMA UE to the R&S
2. Configure the application used to send the TPC commands to the UE (do not yet
start sending TPC commands).
The required signal configuration depends on the TPC setup. For details see
3. Configure the WCDMA TPC measurement (see mandatory settings below).
4. Start the WCDMA TPC measurement.
5. Start sending TPC commands to the UE.
Auto execution is available for some combined signal path measurement modes. If
auto execution is used, this step is performed automatically when the measure-
ment is started.
