If you use the standalone scenario, you may select any monitor mode TPC setup to
perform a monitor mode measurement. The measurement still works correctly if the
monitor mode TPC setup selected in the measurement differs from the monitor mode
TPC setup really executed.
Only if you use the combined signal path scenario, it is important which monitor mode
TPC setup you select in the measurement. The reason is that the measurement dis-
plays the TPC setup parameter of the signaling application. So the parameter deter-
mines which TPC setup is executed by the signaling application.
The following table provides an overview of the monitor mode TPC setups.

TPC Setup Name
Pattern
Closed Loop
Pattern suitable to command the UE to a selected target power, followed
by an alternating pattern when the target power is reached.
Provided by WCDMA signaling application, but not by WCDMA generator.

4.2.6 Limit Settings and Conformance Requirements
Conformance requirements for WCDMA transmitter tests are specified in 3GPP TS
34.121, section 5, "Transmitter Characteristics".
The following sections give an overview of the TPC measurement limit settings and the
related test requirements.

Maximum Output Power Limits (Inner Loop Power)
WCDMA equipment is divided into several power classes. For each power class 3GPP
defines the maximum output power of the UE transmitter (averaged over one slot) and
