3.4.1 General Examples
The LTE multi evaluation measurement is programmed as follows:
●
The measurement is controlled by SCPI commands with the following syn-
tax:
...LTE:MEAS:MEValuation...
●
Use general commands of the type
...:LTE:MEAS...
(no
:MEValuation
mne-
monic) to define the signal routing and perform RF and analyzer settings.
●
After a
*RST
, the measurement is switched off. Use
READ:LTE:MEAS:MEValuation...?
to initiate a single-shot measurement and
retrieve the results. You can also start the measurement using
INIT:LTE:MEAS:MEValuation
and retrieve the results using
FETCh:LTE:MEAS:MEValuation...?
.
●
For synchronization and proper decoding, some UE signal settings must be in
accordance with the measured signal; see
