Aeroflex upgraded its 3920 Radio Test Set to now support P25 Phase II TDMA test functions. The upgrade also includes new features for the development, manufacture, and field-test of analog and digital PMR radios and base stations.

TDMA operation support includes:

  • 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
  • New features for P25 radios have been added, including extended FM analog test functions.

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.
