ifm - UHF RFID reader production testing


Fully Automated UHF Reader Testing During Mass Production

„Several years ago ifm started with RFID. In 2018 ifm was looking for a competent partner in UHF RFID technology and started working with CISC,” says Andre Bixenmann, Technical Manager RFID Systems „Initially using the CISC RFID Xplorer to support the engineering, we recognized that we would like to have the same kind of in-depth testing also for production and asked CISC for a solution.”

„The API control software enabled a convenient integration of a comprehensive reader testing setup during the mass production,” says Tobias Glückler, Teamleader Product Development RFID, „The switch and its possibility to connect contact and contactless RF Sensor Modules allowed us to realize a fully automated production test solution for our comprehensive UHF reader product portfolio.

Integration into a mass production environment

The RFID Xplorer hardware with its core supports a fully configurable tag emulator and auxiliary devices like phase shifter, impedance emulator, and control for multiple RF sensor modules allow all kinds of testing configurations. The software allows comprehensive receiver sensitivity testing under various conditions, as well as transmit power verification, software behavior like channel use, noise measurements and protocol, and software tests including conformance verification. All measurement results and data can be exported for post-processing and production documentation.

Testing of readers on different parameters

Testing with RFID Xplorer helps verify that readers meet the functional, performance, design, and implementation requirements that are identified during deployments. The RFID Xplorer unit is designed for ISO/IEC 18000-63 testing according to ISO/IEC 18046-2, which addresses the testing requirements such as using tag emulation to test readers beyond the tolerances of tag production and without requiring such tags. Beyond this, the use of off-the-shelf readers with default settings and ensuring readers are evaluated on system parameters such as phase shift or self-jamming are possible.
