The UE spurious emissions test is limited by the dynamic range of the signal analyzer, which requires the carrier signal to be filtered out when we measure the spurious emissions of the device under test. However, the terminal has the characteristics of full standards and full spectrum, that is, it has multiple carrier bandwidths and different carrier frequencies. Implementing this through a large number of switch filter combinations has become extremely complex and inefficient.
The UE spurious emissions test system developed by our company integrates a programmable and adjustable band-stop filter combination, supporting multi-carrier bandwidth and multi-carrier frequency band stray and blocking tests. It has a wide coverage and a high degree of test automation, greatly improving test efficiency and reducing labor costs.
