Connected devices and mobile applications require wireless network access that is resilient, secure and able to protect individuals’ privacy. For this reason, a massive number of harmonized standards and specifications have been developed by the wireless industry. Conformance to these standards and specifications is the way to accomplish resilient and secure wireless access.
More specifically, ETSI/3GPP has released an extensive conformance test specifications (TS 136 521-1 for LTE and TS 138 521-1 for 5G NR) that stipulate how and to what levels the radio properties of a mobile device should be verified in order to enable high quality wireless access. Two important objectives for the conformance test specification are to detail requirements applicable for any mobile device with respect to:
Transmitter output spurious emissions
Receiver blocking characteristics
Appropriate testing and conformance to these requirements are needed to safeguard the quality of the wireless access for an individual user as well as for the overall network performance.
In some cases, the performance requirements – and hence the test levels – are so stringent that the capabilities of conventional test instruments are not enough. This is in particular the case for commercially available:
Spectrum analyzers – that do not have the dynamic range needed to fully verify transmitter output spurious emissions
