Testing RF performance

nRF9151 Hardware Verification Guidelines

The RF performance of nRF9151 is designed to meet the 3GPP TS 36.101 and TS 36.102 specifications. RF performance can be tested with a cellular tester that supports RF measurements specified in the 3GPP specification, such as Rohde & Schwartz CMW100 or CMW500.

Nordic Semiconductor has used CMW500 in internal RF performance verification. For details on the options needed on CMW500 for the supported operating modes, see Appendix. For non-signaling mode testing, the Rohde & Schwartz CMW100 can also be used.

Radiated performance should also be verified. This testing requires an anechoic RF chamber and is typically conducted by a test house that provides this service.

The following figure shows an example setup for a signaling mode RF performance test. A separate RF signal generator can be used for Global Navigation Satellite System (GNSS) measurements or the signal can be taken from an LTE tester.
