How to measure an uplink LTE signal with CA
The basic measurement procedure is the same as for signals without carrier aggrega-
tion. Even the test setup is the same.
In addition, consider the following points:
●
In the current software version, carrier aggregation measurements are only possi-
ble with the standalone scenario, not with the combined signal path scenario. List
mode measurements are not supported.
●
Enable carrier aggregation by selecting the "Carrier Aggregation Mode"
●
Select a "Measurement Carrier". This carrier is used for synchronization, so it must
have allocated RBs. The selected carrier is evaluated by single-carrier measure-
ments, for example for measurement of modulation or power dynamics results.
●
Configure the PCC and the SCC center frequency according to the 3GPP rules for
intra-band contiguous CA.
An automatism facilitates the configuration. You only need to configure the band-
widths and the PCC frequency. Then you specify whether the SCC frequency shall
be above or below the PCC frequency and adjust the SCC frequency via a button.

Parallel Signaling and Measurement
The multi evaluation measurement can be used in parallel to the LTE signaling applica-
tion (option R&S CMW-KS500/-KS550), i.e. a connection to the UE can be set up by
the signaling application and the resulting uplink signal can be measured using the
multi evaluation measurement.
To use both applications in parallel, the combined signal path scenario must be activa-
ted (see
"Scenario = Combined Signal Path"
on page 540). Most signal routing and
analyzer settings and some measurement control settings are then configured by the
signaling application. The multi evaluation measurement displays the corresponding
signaling settings instead of its own settings. These signaling settings can be config-
ured both in the measurement GUI and in the GUI of the signaling application.
To configure these settings via remote commands, the commands of the signaling
application must be used. For a command mapping table, see
The most important signaling parameters not relevant for standalone measurements
can nevertheless be configured both in the measurement GUI and in the GUI of the
signaling application. In the measurement GUI they can be accessed via hotkeys.
