The Marconi IFR Aeroflex 1200A is a microprocessor-controlled communication service monitor that consolidates multiple test instruments into a single portable unit. It delivers comprehensive RF signal generation, reception, and analysis capabilities across 250 kHz to 1 GHz, supporting AM, FM, and SSB modulation formats alongside digital signaling (DCS, DTMF, pulsed audio). The instrument operates in both benchtop and field environments, serving land mobile, cellular, and two-way radio maintenance applications.
