Compact system for measuring radiated spurious emissions on LTE devices

The European R&TTE Directive and standardization bodies such as the ITU specify radiated spurious emission (RSE) measurements for wireless communications devices. The conventional approach to measuring RSE uses notch filters to suppress strong wireless carrier signals. However, this approach is impractical for Long Term Evolution (LTE) which uses 258 combinations of frequency bandwidths. Rohde & Schwarz now presents a new test concept that significantly reduces costs and effort.
