This setting determines the slot sequence measured for the power monitor view.
And this setting is important for power dynamics measurements, to measure the OFF
power after the last allocated resource unit, see
Chapter 3.2.3, "Scope of the Measure-
Remote command:
CONFigure:NIOT:MEAS<i>:MEValuation:NSLots
Cyclic Prefix
Only the normal cyclic prefix length is supported.
Channel Bandwidth
Displays the channel bandwidth. The bandwidth is fixed for NB-IoT signals.
Subcarrier Spacing
Selects the subcarrier spacing, 3.75 kHz or 15 kHz. Set this parameter in accordance
with your measured signal.
In the standalone (SA) scenario, this parameter is controlled by the measurement. In
the combined signal path (CSP) scenario, it is controlled by the signaling application.
Remote command:
CONFigure:NIOT:MEAS<i>:MEValuation:SCSPacing

(CSP)
NPUSCH Format
Specifies the format of the NPUSCH, format 1 or format 2.
The format influences for example the allowed resource allocation values, see
ter 3.2.6.2, "Resource Unit Allocation"
If you select an NPUSCH trigger signal as trigger source, the NPUSCH format is set
automatically.
In the combined signal path (CSP) scenario, the signaling application sets the trigger
signal and thus the NPUSCH format automatically. If there is an NPUSCH with format
1 (scheduling type with UL), format 1 is set. If there is no NPUSCH with format 1
(scheduling type with DL only), format 2 is set.
If format 1 is set by the signaling application, but you want to measure format 2, set the
trigger source selection to the format 2 signal.
Remote command:
CONFigure:NIOT:MEAS<i>:MEValuation:NPFormat
Resource Allocation
Configure the settings according to the resource allocation of the measured signal.
Configure the settings in the following order:
●
Subcarrier spacing and NPUSCH format
●
Number of subcarriers
●
Start subcarrier
