Method for testing data packet signal transceivers with multiple radio access technologies using interleaved device setup and testing

Abstract

A method of using tester data packet signals and control instructions for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) capable of communicating using multiple radio access technologies (RATs) having one or more mutually distinct signal characteristics. During mutually alternating time intervals, selected ones of which are substantially contemporaneous, tester data packet signals and control instructions are used for concurrent testing and configuration for testing, respectively, of multiple RATs of the DUT.

Description

Background technique [0001] The present invention relates to testing packet signal transceivers with multiple radio access technologies, in particular to achieve faster test times for such transceivers by using interleaved device setup and testing. [0002] Many of today's electronic devices use wireless technology for both connection and communication purposes. Because wireless devices transmit and receive electromagnetic energy, and because two or more wireless devices may interfere with each other's operation due to their signal frequencies and power spectral densities, these devices and their wireless technology must comply with various wireless technology standard specifications. [0003] When designing these wireless devices, engineers take extra care to ensure that the devices will meet or exceed the specifications set by the standards for each of the wireless technologies they include. In addition, when these wireless devices later enter mass production, they are test...
