A computer-implemented method for synchronizing wireless testing devices includes (a) in a protocol analyzer located in an RF-isolated test chamber, capturing first network packets transmitted to or from a wireless device-under-test (DUT) to generate protocol test data, (b) in the protocol analyzer, determining if any of the first network packets satisfy a trigger rule, (c) in the protocol analyzer, generating a trigger output signal when the trigger rule is satisfied, (d) sending the trigger output signal from the protocol analyzer to an RF analyzer in electrical communication with the DUT, (e) capturing second network packets with the RF analyzer based on the trigger output signal to generate RF test data, the second network packets transmitted to or from the DUT, and (f) in the protocol analyzer, time-aligning the first and second network packets in the protocol test data and the RF test data, respectively.

System and method for synchronizing protocol and RF analyzers during wireless testing

Systems and methods for design and testing of RF components are described. One or more RF isolation chambers are used to house MU-MIMO capable devices under test, including wireless access points and client devices. Spatial and angular positioning of the antennas within a chamber and controlled power of the signals into each antenna via RF combiners and RF attenuators to achieve a controllable apparent/virtual angular spread among the respective client device signals is described.
