2967 Cobham Radio Test Set

The Aeroflex / IFR / Marconi 2967 Radio Test Set supports all the protocols required to perform measurements on GSM 900/1800/1900 MHz systems. In addition, it supports analog cellular standards TACS, AMPS, NMT and the world-wide trunking systems based on MPT 1327.

Based on ETSI GSM11.10 recommendations, the 2967 tests all the essential RF, audio and DC parameters quickly and easily in both Service and Production environments.

Unlike GSM only radio test sets, the 2967 includes a host of RF instrumentation and analog/digital facilities which are invaluable for performing diagnostics, radio alignment and parametric tests.

High-speed testing is ensured by use of pre-programmed test sequences, fully user configurable for depth of test, running on a multi-processor test platform. Further speed enhancements are obtained by performing simultaneous TX or RX measurements over a specified number of bursts using remote control commands.

GSM 900 Phase two testing is fully supported in the 2967.

The 2967 emulates a GSM 900/1800/1900 base station allowing mobiles to be tested in the same way that they operate on a real system without user knowledge of manufacturer specific test modes. Network simulation is especially useful when checking for configuration problems on mobiles. Transmitter tests measure power, peak and RMS phase error, frequency error and timing error, all as specified in GSM11.10. Graphical displays, with fast update rates, show power profile and phase profile against the relevant GSM masks, for both shortened and normal bursts, to aid radio alignment. Receiver testing covers all classes of BER, RBER and FER readings, and automatic sensitivity measurement is also provided.

New system features have been added to test additional terminal facilities, IMSI detach, Cell Barring and Minimum RF level for Access.

The 2967 covers the Phase 2 frequency plan (E-GSM) and supports the lower power levels (PL16-PL19).
