LTE PRACH Measurement
R&S

CMW-KM5xx/-KS5xx
764
User Manual 1173.9628.02 ─ 16
Stop Condition
Specifies the conditions for an early termination of the measurement:
●
None:
The measurement is performed according to its "Repetition" mode and "Sta-
tistic Count", irrespective of the limit check results.
●
On Limit Failure:
The measurement is stopped as soon as one of the limits is
exceeded, irrespective of the repetition mode set. If no limit failure occurs, it is per-
formed according to its "Repetition" mode and "Statistic Count". Use this setting for
measurements that are essentially intended for checking limits, e.g. production
tests.
Remote command:
Measure on Exception
Specifies whether measurement results that the R&S
CMW identifies as faulty or inac-
curate are rejected. A faulty result occurs e.g. when an overload is detected. In remote
control, the cause of the error is indicated by the "reliability indicator".
●
Off:
Faulty results are rejected. The measurement is continued; the statistical
counters are not re-set. Use this mode to ensure that a single faulty result does not
affect the entire measurement.
●
On:
Results are never rejected. Use this mode e.g. for development purposes, if
you want to analyze the reason for occasional wrong transmissions.
Remote command:
Frame Structure
Displays the frame structure of the uplink signal as defined in 3GPP TS 36.211. The
value is set implicitly via the
Remote command:
Channel Bandwidth
Channel bandwidth between 1.4 MHz and 20 MHz. Set the bandwidth in accordance
with the measured LTE signal.
The parameter is a common measurement setting, i.e. it has the same value in all
measurements (e.g. PRACH measurement and multi evaluation measurement).
In the Standalone (SA) scenario, this parameter is controlled by the measurement. In
the Combined Signal Path (CSP) scenario, it is controlled by the signaling application.
Remote command:
(SA)
(CSP)
PRACH Configuration Index
Specifies the PRACH configuration used by the UE. The PRACH configuration defines
the preamble format and other signal properties, e.g. which resources in the time
domain are allowed for transmission of preambles. The resulting preamble format is
displayed for information.
