Keysight Introduces First Test Platform to Validate GCF RF NB-IoT and CAT-M Test Cases

Keysight Technologies recently introduced the T4010S conformance test system, the first and only test platform that includes RF NB-IoT and CAT-M validated test cases together in the Global Certification Forum (GCF). During the most recent Conformance and Interoperability Agreement Group meeting, held in London, the Keysight T4010S conformance test system reached first position in the sum of validated GCF RF NB-IoT test cases and bands as well as first position in RF overall test cases and bands coverage from Rel-8 to Rel-13.

It is the only test platform that has validated RF NB-IoT test cases in all currently existing NB-IoT GCF bands and has become an essential test platform for RF NB-IoT GCF certification because it is the only test platform to provide validated test cases for bands 1,3 and 28.

The T4010S is a complete test solution covering LTE/LTE-Advanced RF and RRM to RF NB-IoT/Cat-M test capabilities according to 3GPP standards during different stages of the product development from early design and verification stages to the full UE certification. The integration of the Keysight UXM network emulator greatly simplifies the development and verification tasks helping customers bring reliable CIoT enabled devices to market more quickly.

The test platform covers conformance testing according to 3GPP TS 36.521-1 LTE, NB-IOT RF and 3GPP TS 36.521-3 LTE RRM for FDD and TDD, 1CC, 2CC, 3CC and 4CC, as well as LTE device acceptance test plans from major network operators. Support of Regulatory for Europe RF EN 301 908-13 is also available on the T4010S.

Engineers can use this system for R&D design verification with the same hardware that is used for conformance testing. It offers the ability to execute test cases with different parameters other than those required by 3GPP. This platform also allows testing for all LTE, NB-IOT frequency bands at no additional cost.

The E7515A UXM wireless test set’s receiver test capabilities, including flexible channel definition, frequency division duplex (FDD), and time division duplex (TDD) options, along with out-of-channel measurements and integrated fading, enable extensive coverage of 3GPP test cases in the conformance benchtop solution.

The test case parameterization environment, test automation, and remote control makes the T4010S conformance test system one of the most flexible tools for RF parametric testing, margin search, and complete system validation. Support of GCF/PTCRB validated test cases (TP 195), allows system users to perform full UE certification.

Key Features of the T4010S Conformance Test System:

  • Complete 3GPP RF test case coverage for RF and RRM according to GCF and PTCRB requirements (TP195)
  • Design verification and supplementary test case coverage
  • Support for 1CC, 2CC, 3CC ,4CC band combinations and beyond
  • Scalable solution – from one box to full system
  • Dual-feed antenna UE support
  • Complete test case results analysis and reporting tools
  • Full test system automation
  • Remote test system operation
