Problems solved by technology

[0006] However, due to differences in synchronization timing between individual devices, and the challenges this presents in the coordinated execution of predetermined test sequences, such approaches are still unable to test multiple devices simultaneously using predetermined test sequences

Abstract

A system and method for initiating testing of a plurality of communication devices. The tester and devices under test (DUTs) are first synchronized as a way of confirming test readiness on the part of the DUTs, Following that, a test sequence is initiated by the tester. The synchronization and test initiation can be accomplished using signals with differing signal magnitudes or device identifiers. The test sequence can be a DUT transmit signal test in which each DUT transmits data packets in accordance with one or more predefined test sequences. Alternatively, the test sequence can be a DUT receive signal test in which the tester transmits data packets to the DUTs with differing signal frequencies or signal magnitudes.

Description

technical field [0001] The present invention generally relates to systems and methods for testing electronic devices. More particularly, the present invention relates to improvements in systems and methods for testing wireless signal transceivers using test platforms composed of hardware, firmware and / or software components. Background technique [0002] Many of today's handheld devices use "wireless connectivity" for telephony, digital data transmission, geolocation, and more. Despite differences in frequency spectrum, modulation method, and power spectral density, wireless connectivity standards all use isochronous packets to send and receive data. Generally, all of these wireless functions are defined by industry-accepted standards such as IEEE 802.11 and 3GPP LTE, which specify the parameters and limits that devices with such functions must adhere to. [0003] At any time during the ongoing development of a device, it may be necessary to test and confirm that the devic...
