The E8900A 5G New Radio (NR) handheld spectrum analyzer covers the landscape of new wireless communication technology with all-new levels of flexibility and efficiency for construction and maintenance of 5G NR systems. Correlative interference analysis with interferometer DF antenna and GPS mapping can locate hard-to-isolate interference signals in max accuracy. Persistence spectrum analysis separates the in-band signal transmission from underlying low-level inference signals in supreme clarity without service interruption. FDD-LTE or TDD-LTE signal demodulation analysis includes channel power, cell ID, 4G frequency- or time- division multiple-access signal analysis, sub-frame spectrum, and special sub-frame indicators
