  • System and method for concurrently testing multiple packet data signal transceivers capable of communicating via multiple radio access technologies
    Patent number: 9319912
    Abstract: System and method for using a shared packet data signal source to test multiple packet data signal transceiver devices under test (DUTs) capable of communicating using multiple radio access technologies (RATs). The signal source provides a packet data signal that includes a plurality of sequential signal segments having respective signal timing parameters and mutually distinct signal characteristics in accordance with the RATs. Based upon the signal timing parameters, at least a portion of each signal segment is routed to a respective one of multiple signal connections for conveyance to a corresponding DUT.
    Type: Grant
    Filed: January 2, 2014
    Date of Patent: April 19, 2016
    Assignee: LITEPOINT CORPORATION
    Inventors: Jonathan Barry Hirst, James L. Banzen, William L. Barker, Jr.

  • System and method for testing radio frequency device under test capable of communicating using multiple radio access technologies
    Patent number: 8788892
    Abstract: System and method for testing a radio frequency (RF) device under test (DUT) communicating using multiple radio access technologies (RATs). Single data signal sequences having characteristics of multiple RATs as prescribed by signal standards are exchanged between a tester and DUT. The tester and DUT process received signal sequences substantially in parallel with their reception. A pattern of contemporaneous signal sequence reception and processing continues for as many RATs as the DUT is capable of supporting.
