Thurlby Thandar PSA1302 1.3GHz is unlike any other
RF spectrum analyser. It builds upon the success of the PSA-T series in
offering a lightweight and truly handheld instrument that incorporates an
extensive feature set. An improved user interface is combined with many new
features and a ruggedized casing. The PSA1302 offers every engineer the
opportunity to own a spectrum analyser regardless of their particular
