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

By using both the AR 7200 and AP 6000 a user can playback the air interface several times selecting each time a different UE and analyze that particular call.



Benefits
  • Saves time during debugging, problem analysis and system optimization
  • Replicates the entire communication's air test environment
  • Provides the ability to repeat a particular tested scenario
  • No physical connection required to Node B, Network or UE
