Fig. 2-71: Synchronization settings
Synchronization Zone
Select the same synchronization zone in all signaling applications that you want to syn-
chronize. "None" means that the application is not synchronized to other signaling
applications.
The PCC and SCC of an LTE signaling application are always synchronized to each
other, independent of this setting.
Synchronizing signaling applications means synchronizing the used system time. This
is useful for example for evaluation of message logs, because the time stamps in the
logs are synchronized.
Synchronizing two LTE signaling applications means also synchronizing the used sys-
tem frame numbers.
Remote command:
Synchronization Offset
Configures the timing offset at cell start, relative to the time zone.
Without offset, the cell signal starts with system frame number 0 and a system time
according to the time zone. With an offset, the cell starts with system frame number 0
plus the offset and a system time according to the time zone plus the offset.
Option R&S CMW-KS510 is required for the PCC setting. Option R&S CMW-KS512 is
required for the SCC setting.
Setting different offsets for PCC and SCC is required for example for performance
requirement tests with carrier aggregation, see 3GPP TS 36.521 section "8.2.1.1.1_A".

2.4.12 Connection Configuration
This section defines parameters for the connection, e.g. the resource configuration to
be allocated to the UE. Most parameters can be reconfigured for an established con-
nection.
