The Marconi IFR Aeroflex 2201R Mobile Service Tester is a specialized instrument for GSM-R (Global System for Mobile Communications – Railway) device testing and verification. It delivers fault analysis, RF measurements, and protocol validation across voice, data, and SMS functions for GSM-R mobile handsets and cab radio systems. The tester simulates Voice Group Call Service (VGCS) at multiple priority levels, Railway Emergency (REC) calls, and measures performance of associated peripherals including optical and acoustical alarms.
