Digital test of ZigBee transmitters: Validation in industrial test environment

This paper presents the validation of a low-cost solution for production test of ZigBee transmitters in industrial environment. The solution relies on 1-bit acquisition of a 2.4GHz signal with a standard digital ATE channel using harmonic sampling. Dedicated post-processing algorithms are then applied on the low-frequency binary vector captured by the ATE to retrieve the RF signal characteristics and implement the tests specified by IEEE Std 802.15.4. Experimental results collected on more than 1.5 thousand pieces of a ZigBee transceiver from NXP Semiconductors are presented.
