Software update for Aeroflex's 2975 radio test set

Release 1.9.2 adds the functionality of an Eye Diagram for P25 Waveform analysis. With this diagram, users can quickly see the C4FM deviation points as well as any offset or imbalance in the four frequency levels corresponding to the C4FM modulation (+/- 600Hz and +/- 1800Hz). 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 option 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 Option 2975OPT29 CQPSK Generate/Receive and Analysis 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, including advanced parametric testing for compatible four-level frequency modulation and interoperability testing of P25 systems. As well as standard analog test features, the 2975 provides P25 trunking support for VHF/UHF/700 and 800 MHz bands, SmartNet™/SmartZone™ support, AES and DES encryption support, control message logging, encryption key management facilities, CQPSK generate and receive testing, and advanced CQPSK analysis for Linear Simulcast Modulation systems.

Created with a modular design, the 2975 is simple to support and upgrade. Its 20 GB internal hard drive maximizes flexibility in storage and recall of setup information and test data. Software upgrades can be downloaded allowing features to be added as new radio-specific tests are developed, reducing ownership and life-cycle costs.
