AR-7200 Air Recorder New solution for WCDMA/GSM Air Interface recording The AR-7200 records the WCDMA/GSM air interface for later reproduction, replicating a real-time environment. It records the radio signals between Node Bs and UEs, stores them in its internal hard disk drives and plays them back in I/Q data. The AR-7200 is the ideal companion for the AP-6000 Air Protocol Analyzer when multiple UEs have to be analyzed during the same period of time. The AR-7200 can also be used with other devices supporting analog I/Q inputs. Key Features • RF down conversion and I/Q demodulation • Store DL & UL I/Q base band signals to Hard Disk Drive (HDD) • Play back I/Q base band signals from HDD for analysis with an AP-6000 • Functions on frequency bands I, II, III, V, VI and IX in 3GPP UMTS/WCDMA • Dual RF units • 12-bit analog to digital converter / 14-bit digital to analog converter • Up to 1 hour of recording (2 frequencies) • 2 buffer modes (single or ring) • Data export/import function • WCDMA cell search function
