When the dialog box has been disabled, you can still change the target measurement
or re-enable the dialog box using the configuration menu, see
Go to / Cancel
Press the "Go to" button to switch to the selected measurement or "Cancel" to abort.

General Settings
Access: "NB-IoT Signaling" softkey > "Config" hotkey > top of the configuration dialog.
The general settings are at the top of the configuration dialog. Configure them accord-
ing to your test scenario, before configuring any other settings.
Figure 2-20: Top of dialog
The general settings are described in the following.
Scenario
Different test scenarios require different sets of parameters. Selecting a scenario hides/
shows parts of the GUI as required by the scenario. The active scenario determines,
for example, whether fading is used. It determines also the number of component carri-
ers.
The current software version supports only the "Standard Cell" scenario.
●
"Standard Cell"
:
Standard LTE cell with one RF input path and one RF output path.
●
"Standard Cell Fading"
:
"Standard Cell" plus fading and/or AWGN insertion.
Options R&S
CMW-KE100/-KE500 are required.
An additional parameter "Fader" is displayed, refer to
.
●
"1CC - Fading - 2x1"
:
Tx diversity with fading: Two signals of one NB-IoT cell transmitted via two antenna
ports are faded and combined to one RF output connector.
Tx diversity increases the signal to noise ratio at the receiver side and thus the
robustness of data transmission with fading.
An additional parameter "Fader" is displayed, refer to
.
Options R&S
CMW-KE100/-KE500 are required.

Fading
This parameter is displayed for the fading scenarios. Only internal fading is supported.
