3 LTE Multi Evaluation Measurement
The "LTE Multi Evaluation" measurement provides quick and flexible TX tests on LTE
FDD and TDD uplink signals and an RX test (Block Error Ratio test). The TX tests
cover the following UE transmitter properties:
●
UE output power for each resource block (Inband Emissions)
●
UE output power per subframe (Power Monitor)
●
PUCCH/PUSCH OFF power, PUCCH/PUSCH ON power, SRS OFF power, SRS
ON power (Power Dynamics)
●
UE power variation across the allocated subcarrier range (Equalizer Spectrum Flat-
ness)
●
Modulation accuracy for each SC-FDMA symbol (EVM, Magnitude Error, Phase
Error)
●
Modulation accuracy for each subcarrier (EVM vs. Subcarrier)
●
I/Q Constellation diagram
●
Overview of allocated resource blocks (RB Allocation table)
●
Out-of-band emissions (Spectrum Emission Mask and ACLR)
Many of the tests and conformance requirements are specified in 3GPP TS 36.101 or
3GPP TS 36.521.
The multi evaluation measurement requires option R&S CMW-KM500 for FDD signals
and R&S CMW-KM550 for TDD signals.
3.1 What's New in this Revision
This revision describes version 3.2.80 and later of the "LTE Multi Evaluation Measure-
ment" firmware application. Compared to version 3.2.70, it provides the following new
features:
●
PUCCH / PUSCH / SRS time mask and SRS blanking time mask also for TDD, see
●
Peak values of the EVM vs subcarrier trace are available via remote commands,
see
●
Spectrum emission mask: maximum number of areas per mask enhanced from 10
to 12, see
Software Version
To check your R&S
CMW software version, open the "Setup" dialog and click "HW/SW
Equipment". The initial software version for each remote control command is quoted in
the reference description.
