The Marconi IFR Aeroflex 2960B Radio Communication Test Set is a dual-purpose instrument for signal generation and receiver analysis across radio communication systems up to 1 GHz. It combines AM/FM signal generation, modulation analysis for analog and digital modes, RF power measurement, and spectrum analysis in a single platform. Built on established Marconi and IFR radio test technology, the 2960B delivers signal generation accuracy, automatic modulation detection, and sensitive receiver measurements required for field and bench-top radio servicing.
