Abstract
A method of using tester data packet signals and control instructions for testing multiple data packet signal transceiver devices under test (DUTs). During mutually alternating time intervals, selected ones of which are substantially contemporaneous, multiple tester data packet signals and DUT control instructions are used for concurrent testing of multiple DUTs.
Claims12
A method of using tester data packet signals and control instructions for testing multiple data packet signal transceiver devices under test (DUTs), comprising:
- receiving, with each one of first one or more of a plurality of DUTs with data packet signal reception enabled during one of a first plurality of tester signal intervals, a respective one of a plurality of tester data packet signals;
- receiving, with each one of second one or more of said plurality of DUTs with data packet signal reception enabled during one of a second plurality of tester signal intervals, a respective one of said plurality of tester data packet signals;
- executing, with each one of said first one or more of said plurality of DUTs with data packet signal reception disabled during one of a first plurality of instruction intervals, a plurality of DUT control instructions to configure each one of said first one or more of said plurality of DUTs to receive a respective one of said plurality of tester data packet signals with one or more of an upcoming prescribed power level, data rate or modulation type;
- and
- executing, with each one of said second one or more of said plurality of DUTs with data packet signal reception disabled during one of a second plurality of instruction intervals, a plurality of DUT control instructions to configure each one of said second one or more of said plurality of DUTs to receive a respective one of said plurality of tester data packet signals with one or more of an upcoming prescribed power level, data rate or modulation type;
- wherein
- respective ones of said first plurality of tester signal intervals and said first plurality of instruction intervals are mutually alternating,
- respective ones of said second plurality of tester signal intervals and said second plurality of instruction intervals are mutually alternating,
- respective ones of said first plurality of tester signal intervals are substantially contemporaneous with respective ones of said second plurality of instruction intervals, and
- respective ones of said second plurality of tester signal intervals are substantially contemporaneous with respective ones of said first plurality of instruction intervals.

A method of providing tester data packet signals and control instructions for testing multiple data packet signal transceiver devices under test (DUTs), comprising:
- providing, for each one of first one or more of a plurality of DUTs with data packet signal reception enabled during one of a first plurality of tester signal intervals, a respective one of a plurality of tester data packet signals;
- providing, for each one of second one or more of said plurality of DUTs with data packet signal reception enabled during one of a second plurality of tester signal intervals, a respective one of said plurality of tester data packet signals;
- providing, for execution by each one of said first one or more of said plurality of DUTs with data packet signal reception disabled during one of a first plurality of instruction intervals, a plurality of DUT control instructions to configure each one of said first one or more of said plurality of DUTs to receive a respective one of said plurality of tester data packet signals with one or more of an upcoming prescribed power level, data rate or modulation type;
- and
- providing, for execution by each one of said second one or more of said plurality of DUTs with data packet signal reception disabled during one of a second plurality of instruction intervals, a plurality of DUT control instructions to configure each one of said second one or more of said plurality of DUTs to receive a respective one of said plurality of tester data packet signals with one or more of an upcoming prescribed power level, data rate or modulation type;
- wherein
- respective ones of said first plurality of tester signal intervals and said first plurality of instruction intervals are mutually alternating,
- respective ones of said second plurality of tester signal intervals and said second plurality of instruction intervals are mutually alternating,
- respective ones of said first plurality of tester signal intervals are substantially contemporaneous with respective ones of said second plurality of instruction intervals, and
- respective ones of said second plurality of tester signal intervals are substantially contemporaneous with respective ones of said first plurality of instruction intervals.
