3. To initiate the handover press the "Handover" key in the dialog.
The WCDMA CS connection state changes from "Call Established" to "Outgoing
Handover in Progress", while the GSM CS connection state changes from "ON" to
"Incoming Handover in Progress".
When the handover has been completed, the WCDMA CS state changes to "ON",
the GSM CS state to "Call Established" and the GSM cell state to "ON".
2.3.3 Inner Loop Power Control Tests
This application sheet describes how to perform a WCDMA inner loop power control
test, as defined in 3GPP TS 34.121, section 5.4.2.
2.3.3.1
Options and Equipment Required
A WCDMA inner loop power control test requires the following equipment:
●

ware version
≥
V2.1.20. The latest software version is recommended. This applica-
tion sheet describes software version V3.0.20.
The tester must be equipped with a wideband signaling unit.
●
Option R&S CMW-KS400, "WCDMA R99, basic signaling"
●
Option R&S CMW-KM400, "WCDMA R99, TX measurement, uplink"
2.3.3.2
Test Overview
In CDMA networks, control of the UE transmit power is essential to ensure stable
transmission and an efficient radio resource management within the system.
For that reason the Node B controls the UE power via the transmission of Transmit
Power Control (TPC) commands on the DL DPCH. The UE is expected to adjust its
transmit power according to the received TPC commands.
