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.
Claims18
An apparatus including a system for testing a plurality of radio frequency (RF) packet data signal transceiver devices under test (DUTs) capable of communicating using a plurality of radio access technologies (RATs), comprising:
- a plurality of signal connections to convey at least respective portions of a packet data signal to respective ones of a plurality of DUTs;
- a packet data signal source to provide said packet data signal, wherein said packet data signal includes a plurality of sequential signal segments having respective signal timing parameters including at least segment timing boundaries separating adjacent signal segments, and having mutually distinct signal characteristics in accordance with a plurality of RATs;
- signal routing circuitry coupled between said packet data signal source and said plurality of signal connections, and responsive to at least one or more routing control signals by routing at least one of said plurality of sequential signal segments to a respective one of said plurality of signal connections;
- and
- control circuitry coupled to said signal routing circuitry to provide said one or more routing control signals in accordance with which
- at least a portion of a first one of said plurality of sequential signal segments is routed to a first one of said plurality of signal connections during a first time interval related to a first one of said respective signal timing parameters, and
- at least a portion of a second one of said plurality of sequential signal segments is routed to a second one of said plurality of signal connections during a second time interval related to a second one of said respective signal timing parameters.
A method of testing a plurality of radio frequency (RF) packet data signal transceiver devices under test (DUTs) capable of communicating using a plurality of radio access technologies (RATs), comprising:
- generating a packet data signal that includes a plurality of sequential signal segments having respective signal timing parameters including at least segment timing boundaries separating adjacent signal segments, and having mutually distinct signal characteristics in accordance with a plurality of RATs;
- responding to at least one or more routing control signals by routing at least one of said plurality of sequential signal segments to a respective one of a plurality of DUTs;
- and
- generating said one or more routing control signals in accordance with which
- at least a portion of a first one of said plurality of sequential signal segments is routed to a first one of said plurality of DUTs during a first time interval related to a first one of said respective signal timing parameters, and
- at least a portion of a second one of said plurality of sequential signal segments is routed to a second one of said plurality of DUTs during a second time interval related to a second one of said respective signal timing parameters.
