NB-IoT NPRACH Measurement

The NB-IoT NPRACH measurement provides quick and flexible tests on NB-IoT FDD
random access preambles. The tests cover the following UE transmitter properties:

●

Modulation accuracy for each NPRACH symbol (EVM, magnitude error, phase
error)

●

Transmit OFF power, transmit ON power and power ramping between them (power
dynamics)

●

I/Q constellation diagram

The NPRACH measurement requires option R&S CMW-KM300.

What's New in This Version

This documentation describes version 3.7.40 and later of the NB-IoT NPRACH mea-
surement. Compared to version 3.7.30, it provides only editorial changes.

4.2

 

General Description

The NB-IoT NPRACH measurement captures an uplink (UL) NPRACH signal and pro-
vides TX measurement results for the random access preambles. Only FDD signals
can be measured. Option R&S CMW-KM300 is required.

The following sections describe how to perform and configure the measurement.

Test Setup

Connect the external RF signal source (mobile station, signal generator etc.) to one of
the bidirectional RF connectors on the front panel of the R&S

 

CMW.

4.2.2

 

How to Measure an Uplink NPRACH Signal

The measurement expects an NB-IoT NPRACH UL signal. Any other signals do not
yield measurement results (e.g. an NB-IoT UL signal for an established connection).
