2.3.3 Performing Signaling Measurements
The purpose of a signaling application is to establish a network connection to a mobile
station in order to perform various tests. All signaling applications are controlled in an
analogous manner.
As an example we set up a connection to a UE via the WCDMA signaling application.
Then we use the WCDMA multi evaluation measurement to analyze the uplink signal.
To perform a WCDMA signaling measurement,
1. Open the "WCDMA Signaling" application, e.g. from the task bar (press "TASKS" to
open the task bar).
If the application is not present in the task bar, enable it in the "Generator/Signaling
Controller" dialog (press "SIGNAL GEN" to open the dialog).
2. In the main view of the signaling application adjust the "Cell Setup" settings to the
capabilities of your UE.
The "Frequency" must be supported by the UE and the "Output Power" must be suf-
ficient.
3. Press the "Config" hotkey to open the configuration dialog.
4. In section "RF Settings" select a bidirectional RF connector for input and output. In
this example RF 1 COM is used. If necessary, also adjust the "External Attenua-
tion" settings.
5. Close the configuration dialog.
6. Connect your UE to the RF 1 COM connector.
7. To turn on the DL signal press "ON | OFF" and wait until the "WCDMA-UE Signaling"
softkey indicates the "ON" state and the hour glass symbol has disappeared.
8. Switch on the UE.
The UE synchronizes to the DL signal and registers. Note the connection states dis-
played in the main view and wait until registration is complete.
After the UE has registered, the main view provides UE information, the UE mea-
surement report and UE capability information.
