Group Hopping
Specifies whether group hopping is used or not (refer to "group hopping" in 3GPP TS
36.211). Set this parameter according to the measured LTE signal to ensure that the
R&S
CMW can synchronize to the signal and perform channel estimation.
Measurements with group hopping require a frame trigger signal.
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)
Measurement Subframe
Configures the scope of the measurement, i.e. which subframes are measured.
●
Subframe Offset
: specifies the start of the measured subframe range relative to
the trigger event
●
No. of Subframes
: specifies the length of the measured subframe range, i.e. the
number of subframes
–
to be measured and displayed in the views "Power Monitor" and "RB Allocation
Table"
–
to be evaluated for BLER measurements (select a high value being a multiple
of 10 - to speed up BLER measurements and ensure that the number of sched-
uled subframes per radio frame can be evaluated correctly)
●
Measure Subframe
: selects one subframe of the measured subframe range con-
taining the measured slots for all other results, e.g. modulation and spectrum
results. For "Power Dynamics" measurements the ON power is measured in this
subframe.
