Abstract
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.
