3.2 General Description
The LTE "Multi Evaluation" measurement captures an uplink (UL) LTE signal and pro-
vides the TX measurement results for a configurable UL subframe / range of sub-
frames.
Both FDD signals (option R&S CMW-KM500) and TDD signals (option R&S CMW-
KM550) can be measured. For signals with uplink carrier aggregation, an additional
option is required (R&S CMW-KM502 for FDD, R&S CMW-KM552 for TDD).
With an additional ARB generator, it is also possible to perform Block Error Ratio
(BLER) measurements (RX tests).
The following sections describe how to perform and configure the measurement.

TX tests have many characteristics in common. The following sections describe these
characteristics and show how to perform TX tests.
3.2.1.1
Test Setup
The external RF signal source (mobile station, signal generator etc.) is connected to
one of the RF input connectors (RF COM) at the front panel of the R&S
CMW. No
additional cabling and no external trigger is needed.
The input level ranges of all RF COM connectors are identical.
