Abstract
The invention described herein utilizes devices under test (DUTs) outfitted with stored, predefined test sequences, testers equipped with vector-signal generation (VSG) and vector-signal analysis (VSA) functionality, and novel methods for combining loopback and single-ended test functions in order to obtain higher testing efficiency for DUTs using Bluetooth or other time-division duplex (TDD) based communications.
Claims24
A method of testing a plurality of communication devices in a test period, comprising:
- transmitting a sequence of data packets from a testing device;
- replicating in parallel the sequence of data packets to create a parallel sequence of data packets;
- transmitting each parallel sequence of data packets to a respective one of a plurality of devices under test (DUTs);
- repackaging the received sequence of data packets and transmitting the repackaged data packets from each one of the plurality of DUTs to the tester;
- and
- determining a faulty DUT from the plurality of DUTs by evaluating whether a repackaged data package has been forwarded from a respective DUT within the test period.
