The diagram displays one result value per "Update Interval". The number of subframes
per interval is configurable. The number of subframes per measurement cycle is also
configurable ("Window Size", number of subframes on the X-axis).
You can enable/disable the display of the individual traces via the softkey - hotkey
combination "Display > Select Trace".
Table
The throughput table indicates statistical throughput results for downlink and uplink.
The "Bytes" value indicates the number of bytes that the R&S CMW has transmitted
(DL) or received (UL) since the measurement was started.
Statistical Results
The statistical values are calculated as follows:
●
Current: Value obtained in the last update interval
●
Average: Average of all "Current" values within the last measurement cycle (win-
dow size)
●
Minimum, Maximum: Largest or smallest "Current" value since the start of the
measurement

2.3.1 Combined Signal Path Measurements
This application sheet describes how to establish a connection to an LTE User Equip-
ment (UE) and perform TX measurements on the received uplink signal using the "LTE
Multi Evaluation" measurement. For SRS and PRACH measurements, see
chap-
ter 2.3.1.5, "SRS and PRACH Measurements" , on page 79.
Sequencer tool R&S CMWrun
The automated test capabilities of R&S CMWrun make many measurement tasks eas-
ier. Option R&S CMW-KT055 provides configurable LTE test modules and test plans
for R&S CMWrun.
