The tools are designed to support both internal pre-testing to confirm the conformity of 5G and sub-6 GHz LTE modules and UEs before the official 3GPP conformity test, and to enable the R&D division to improve receiver sensitivity and performance.
Development Background
Alongside the surge in 5G smartphone orders, annual orders for 5G customer premises equipment (CPE) are also increasing, driven by mobile operators' fixed wireless access (FWA) services. Furthermore, automotive electronics manufacturers are developing 5G communication modules, such as the telematics control unit (TCU). In addition to this growing market for 5G modules and UEs, these same manufacturers are continuing to develop LTE modules and UEs for mobile operators that have not yet launched 5G services.
To sell 5G and LTE UE modules, these equipment manufacturers must ensure that their products pass the 3GPP RF conformity test managed by a certified testing organization.
Conformance testing is the final evaluation of a product before its commercial launch, and if it fails, it may need to be redesigned and retested. Therefore, pre-testing during development is essential to mitigate this risk.
A vector signal generator is needed to generate interference waveforms in pre-testing. Evaluation using interference waveforms is important to suppress receiver sensitivity degradation and helps ensure the development of competitive UEs and modules.
Anritsu has developed these two 3GPP-compliant interference waveform pattern tools to help non-specialist engineers generate interference waveforms to facilitate interference testing.
Product summary
The MG3710E vector signal generator allows receiver sensitivity and interference testing by outputting modulation waveforms up to 6 GHz, and these new interference waveform pattern software tools facilitate the output of different types of signals.
The MG3710E, together with Anritsu's ME7873 series RF conformance testing system , compatible with 5G and LTE systems, can perform RF conformance testing by certification organizations, such as testing entities.
