Abstract

A system and method for testing multiple-input-multiple-output (MIMO) devices under test (DUTs) with multiple radio frequency (RF) signal testers. Each tester receives one or more RF signals from one or more of the DUTs, and the testers are mutually coupled in a ring such that successive ones receive a trigger input signal from an upstream tester and provide a trigger output signal to a downstream tester. Each tester is responsive to its input trigger signal and its one or more RF signals by providing its output trigger signal such that its output trigger signal has an asserted state initiated in response to an assertion of its input trigger signal and a transcending of a predetermined magnitude by at least one of the one or more RF signals.

Description

technical field [0001] The present invention generally relates to systems and methods for testing electronic instruments. More particularly, the present invention relates to improvements to systems and methods for testing wireless signal transceivers using test platforms consisting of hardware, firmware and / or software components. Background technique [0002] Many of today's handheld devices use wireless "connections" for telephony, digital data transfer, geolocation, and more. Despite differences in spectral range, modulation method, and power spectral density, wireless connectivity standards transmit and receive data in isochronous packets. In general, all of these wireless functions are defined by industry-accepted standards, such as IEEE802.11 and 3GPP LTE, which specify the parameters and limits that devices with the above functions must comply with. [0003] At any point in the continuous process of device development, it may be necessary to test and verify that the...
