Aeroflex upgrades digital radio test set

Aeroflex Incorporated announced that an upgrade to its 3920 Radio Test Set supports P25 Phase II TDMA test functions and adds features for the development, manufacturing, and field test of both analog and digital private mobile radios (PMRs) and base stations.

The 3920 Radio Test Set modularity tests all PMR analog and digital radio standards within one test system. Using Aeroflex Auto-Test II scripts, the 3920 also supports automated testing and alignment of TETRA, P25, DMR, dPMR, NXDN™, as well as many analog legacy radio systems.

The 3920 Radio Test Set software version 2.0.0 adds features:
>>P25 Phase II TDMA operation support added, including:

• H-CPM (inbound modulation) modulation and demodulation
• H-CPM eye diagram, distribution plot, and constellation
• H-DQPSK (outbound modulation) modulation and demodulation
• H-DQPSK eye diagram, distribution plot, and constellation
• Generation of all H-CPM standard patterns
• Generation of all H-DQPSK standard patterns
• Unit-under-test (UUT) measurements for Phase II including modulation fidelity, symbol deviation, symbol clock error, frequency error, power, and TX bit error
• Power profile diagrams of both full slots and ramp-up/ramp-down for H-CPM modulation
• Extended FM analog test functions for P25 radios.

>>Analog Duplex: New IF and audio filters emulate the Agilent 8920 test set, allowing older test platform users to upgrade to the Aeroflex 3920.
>>Support for DMR systems such as MOTOTRBO® includes new
analog test features to  eliminate the need to switch between the 3920’s analog and DMR digital test modes.   
>>Enhanced Auto-Test II support for Motorola APX™ Series, XTS-5000®, and other Auto-Test scripts provide enhanced, automated test and alignment features for a wide range of installed radio systems and standards.

Version 2.0.0.1 is compatible with all 3901, 3902 and 3920 models of the 3900 Series product line.
