18. This UCTT SA provides over the air measurements for a quick RF performance characterization of the RF Environment. This function is especially useful in testing cell sites which are not easily accessible. The FFT Spectrum analyzer with wideband analysis bandwidth takes 15 MHz snapshots, not sweeps, of spectrum. A must for wideband signal analysis and interference monitoring. 18
