CL Development Line

Modular test-, measuring, and analysis solutions for the development of NFC interfaces

  • Unique 3D and 2D visualization of the magnetic field
  • Integration and optimization of antennas
  • Testing functionality of NFC-enabled items and interfaces
  • Validation of interoperability according to standards (EMVCo, NFC Forum, CEN)
  • Visualization and analysis of NFC communication (analog, protocol, application)
  • Use Cases
  • Design Validation
  • Interoperability Testing
  • Pre-Conformance Testing
  • Functional Testing

NFC can only work fine if the involved interfaces are designed properly with respect to field coverage, reader sensitivity, interoperability, and functionality. CL Development Line provides means to validate all these aspects of NFC design.

 

Modular Concept

 

Operating Volume of NFC Devices

 

The operating volume defines the three-dimensional space in which an NFC-enabled device running in poll mode is able to communicate with an NFC listener.

To achieve the required operating volume, the strength of the radiated magnetic field and the sensitivity of readers must be sufficiently high.

 
 
 

Design & Validate the Reader´s Operating Volume with COMPRION

Design Validation Center together with the calibrated  CL Development line hardware provides measuring means for designing and validating an NFC operating volume according to the requirements of the application:

  • 2D and 3D visualization of the magnetic field
    (strength and direction)
  • Measurement of reader sensitivity

It comes with:

  • Unique 3D Vector Field Probe
  • Flexible robot interface
  • Oscilloscope for analog signal analysis

Interoperability Testing

Do you have doubts that interacting NFC items are not compatible with each other? Or does it seem that they do not completely understand each other? Or do you just want to have a look into the data exchanged on the contactless interface to understand what is going on?

All this issues can be clarified with COMPRION interoperability testing tools.

 

NFC Interoperability Testing with COMPRION

COMPRION's solution for interoperability testing on the contactless interface shows in a convenient way if partners talking via the NFC interface speak the same language and if there are communication errors. It provides a protocol analyzer for debugging real NFC communication on all NFC layers.

It offers comprehensive measurements and analysis features, such as:

  • Recording, visualization, and interpretation of signals and exchanged data on all levels
    (analog/protocol/application)
  • Analysis of the analog signal and NFC quick measurements

The solution consists of:

  • CL Verify A, designed for the development of contactless interfaces
  • COMPRION's monitoring antennas, especially designed for spying into NFC communication
  • COMPRION's Interoperability Test Center, a software which is able to interpret and analyze the traced binary data and the analog signal

Conformance Testing

Standardization bodies such as NFC Forum, EMVCo, and ISO specify standards for the implementation of NFC technology. They also define the testing for checking if the implementation has been done successfully in conformance with this standards. This procedure is named conformance testing and is done at certified test houses.

 

Pre-Conformance Testing with COMPRION

COMPRION offers the appropriate hardware and software to execute this conformance tests already during development in the lab. The Device Test Center software comes with the same test benches used for analog and digital conformance testing at test houses:

  • EMVCo
    - PICC Level 1
    - PCD Level 1
  • NFC Forum
    - Digital Protocol
    - Tag Operation
    - LLCP, SNEP
    - RF Analog
  • CEN TS 16794-2 (ISO/IEC 10373-6)

CL Development Line allows to run this test benches in the own lab on calibrated measuring devices. So, conformity with standards during development can be proven at an early stage and costs for repeated test sessions in test houses are reduced.

Functional Testing

Individual functions of an NFC-enabled device are out of the scope of the tests defined by standardization bodies such as NFC Forum or EMVCo. But this functionality must also be tested to achieve a good overall quality of the respective components. For extending test coverage beyond conformance standards, programming interfaces are needed, which allow creating individual test scenarios. 

 

Functional Testing with COMPRION

For this purpose, the hardware components of CL Development Line are controlled by Device Test Center.


Together with the NFC Test Designer, a bunch of useful tools are offered:

  • Write customized test scripts (XML) without extensive programming skills
  • NFC Test Step Editor with code completion for easier editing and better readability
  • NFC Analyzer Editor (JavaScript) for creating analyzers
  • Capture, edit, and replay NFC communication:
    Editor allows to derive new test scripts from captured communication
