Comprehensive Testing Environment (CTE)


Comprehensive Testing Environment (CTE)

The CTE is the heart for all our supported Test Plans. CTE consists of a powerful test plan framework, which executes test plans on different hardware environments. This framework offers online path compensation for high accuracy and full automation of multiple Device under Test and System Configuration for Repetability, Reproducibility and Efficiency. Test Plans can be easily added and coverage scaled up to full Conformance and Network Operator Coverage Even the smallest Hardware Environment (HWE 3000, Aeroflex 7100 standalone) covers more than 85% of LTE RF Conformance Requirements for about 20% of the price of comparable Conformance Test Systems. Upgrade Paths are available for a variety of technology dependent RF & Performance Test Plans in 2G, 3G, Bluetooth, WLAN, AGPS, LTE and LTE Advanced  

CTE Test Solutions in the complete development chain







Pre-Conformance meeting 3GPP or Regulatory Requirements

Test Cases are implemented and verified against Conformance Specification and References. The Test Cases fulfils Conformance Requirements of highlighted Specification and offers a uniquely large variety of Parameter Flexibility while keeping the Measurement Uncertainty and Quality of Tests according to Conformance Requirements


  • Scalable and editable parameters in GUI
  • Test time reduction due to scalable parameters
  • User editable warning limits
  • Customizing / Custom R&D Tests
  • Absolute limit search feature
  • Editable calibration interval
  • Regression Testing




Test Cases are conform and have been validated according to GCF & PTCRB/PVG (Test Platform TP67 for 2G, TP86 for (A)GPS and TP123 for LTE endorsed), Regulatory Requirements (like R&TTE, FCC and Japanese Radio Law) and Network Operator Requirements (like VzW).
