Figure 3-2: Measured slots with No. of Measure Slots = 20
If you set the number of measured slots to 16, you get the same results as with 20
slots - at least for modulation, spectrum and power dynamics results. The change
would only affect the power monitor, where you would see 16 slots instead of 20 slots.

Parallel Signaling and Measurement
You can use the multi-evaluation measurement in parallel to the NB-IoT signaling appli-
cation (option R&S CMW-KS300). Set up a connection to the UE with the signaling
application. Then measure the resulting uplink signal with the multi-evaluation mea-
surement.
To use both applications in parallel, the combined signal path scenario must be activa-
ted (see
"Scenario = Combined Signal Path"
on page 226). Most signal routing and
analyzer settings and some measurement control settings are then configured by the
signaling application. The multi-evaluation measurement displays the corresponding
signaling settings instead of its own settings. These signaling settings can be config-
ured both in the measurement GUI and in the GUI of the signaling application.
To configure these settings via remote commands, use the commands of the signaling
application. For a mapping table, see
Chapter 3.5.4, "Combined Signal Path Com-
The most important signaling parameters not relevant for standalone measurements
can nevertheless be configured both in the measurement GUI and in the GUI of the
signaling application. In the measurement GUI, they can be accessed via hotkeys.
Whenever the combined signal path scenario is activated or the controlling application
is changed, the frame trigger signal provided by the controlling signaling application is
selected automatically as trigger source.
3.2.5
List Mode
The NB-IoT multi-evaluation list mode requires option R&S CMW-KM012. In this mode,
the measurement interval is subdivided into segments, according to basic uplink signal
properties like expected power, frequency and NPUSCH configuration (format,
resource units, subcarriers, repetitions).
