Aeroflex adds software update to 2975 test set
By Staff -- Test & Measurement World, 10/1/2006
Aeroflex has announced a new software version—Release 1.9.2—for its 2975 Project 25 radio test set. The new software adds eye-diagram functionality for P25 waveform analysis. With this diagram, users can quickly see the C4FM (compatible four-level frequency modulation) deviation points as well as any offset or imbalance in the four frequency levels corresponding to C4FM modulation (±600 Hz and ±1800 Hz). This new eye diagram feature is included in Option 2975OPT30 Modulation Analysis and is free of charge.
In addition, Release 1.9.2 has a new configuration to simplify the ordering of LSM testing options. Options 11 (LSM/Phase 2) and 13 (LSM Advanced/P25 Phase 2 Advanced) have now been combined into a single option—the 2975OPT29 CQPSK (compatible quadrature phase shift keying) Generate/Receive and Analysis option, which provides tests for linear simulcast modulation.
The 2975 is a digital radio test platform that tests radio equipment to ensure proper operation to various Project 25 standards (www.p25.com), including parametric testing for compatible four-level frequency modulation and interoperability testing of P25 systems.
Base prices: 2975—$21,495; Release 1.9.2—free; 2975OPT30 Modulation Analysis option—free; 2975OPT29 CQPSK Generate/Receive and Analysis option—$8000. Aeroflex, www.aeroflex.com.
