Options and Equipment Required
An LTE combined signal path measurement requires the following equipment:
●
Wideband Radio Communication Tester R&S CMW500 with software version
≥
V1.0.15.20. The latest software version is recommended.
This application sheet describes software version V3.2.10.
●
Option R&S CMW-KS500, LTE FDD R8, basic signaling
or option R&S CMW-KS550, LTE TDD R8, basic signaling
●
Option R&S CMW-KM500, LTE FDD R8, TX measurement
or option R&S CMW-KM550, LTE TDD R8, TX measurement
The following sections describe a combined signal path measurement for FDD. A com-
bined signal path measurement for TDD is performed in the same way, using the R&S
CMW-Kx550 options instead of the R&S CMW-Kx500 options.

Setting up a Connection
An established connection to the UE is a prerequisite for many signaling tests, includ-
ing the combined signal path measurement described in this application sheet. The fol-
lowing example uses a single downlink stream. For MIMO tests, additional cabling and
related configuration of routing settings are required.
To set up a connection,
1. Reset your R&S
CMW to ensure a definite instrument state.
2. Connect your UE to the RF 1 COM connector.
3. Open the "LTE 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).
4. In the main view of the signaling application, adjust the RF settings to the capabili-
ties of your UE.
Configure especially the duplex mode (FDD / TDD), the band, the channel and the
cell bandwidth. The "RS EPRE" must be sufficient so that the UE under test can
receive the DL signal.
5. Press the "Config" hotkey to open the configuration dialog.
