Method for testing data packet signal transceivers with multiple radio access technologies using interleaved device setup and testing
View Patent ↗A method of using tester data packet signals and control instructions for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) capable of communicating using multiple radio access technologies (RATs) having one or more mutually distinct signal characteristics. During mutually alternating time intervals, selected ones of which are substantially contemporaneous, tester data packet signals and control instructions are used for concurrent testing and configuration for testing, respectively, of multiple RATs of the DUT.
1. A method of using tester data packet signals and control instructions for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) capable of communicating using multiple radio access technologies (RATs) having one or more mutually distinct signal characteristics, comprising:
communicating, via a DUT during one of a first plurality of test intervals, at least one of a first tester data packet signal and DUT data packet signal having a first plurality of signal characteristics in accordance with a first one of a plurality of RATs;
communicating, via said DUT during one of a second plurality of test intervals, at least one of a second tester data packet signal and DUT data packet signal having a second plurality of signal characteristics in accordance with a second one of said plurality of RATs;
executing, with said DUT during one of a first plurality of instruction intervals, a plurality of DUT control instructions to configure said DUT to communicate said at least one of a first tester data packet signal and DUT data packet signal; and
executing, with said DUT during one of a second plurality of instruction intervals, another plurality of DUT control instructions to configure said DUT to communicate said at least one of a second tester data packet signal and DUT data packet signal;
wherein
respective ones of said first plurality of test intervals and said first plurality of instruction intervals are mutually alternating,
respective ones of said second plurality of test intervals and said second plurality of instruction intervals are mutually alternating,
respective ones of said first plurality of test intervals are substantially contemporaneous with respective ones of said second plurality of instruction intervals, and
respective ones of said second plurality of test intervals are substantially contemporaneous with respective ones of said first plurality of instruction intervals.
2. The method of claim 1 , wherein:
respective ones of said first and second pluralities of test intervals are mutually alternating; and
respective ones of said first and second pluralities of instruction intervals are mutually alternating.
3. The method of claim 1 , wherein said respective ones of said first and second pluralities of test intervals are mutually exclusive.
4. The method of claim 1 , wherein said respective ones of said first and second pluralities of instruction intervals are mutually exclusive.
5. The method of claim 1 , wherein said respective ones of said first and second pluralities of instruction intervals are partially contemporaneous.
6. A method of providing tester data packet signals and control instructions for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) capable of communicating using multiple radio access technologies (RATs) having one or more mutually distinct signal characteristics, comprising:
communicating, with a DUT during one of a first plurality of test intervals, at least one of a first tester data packet signal and DUT data packet signal having a first plurality of signal characteristics in accordance with a first one of a plurality of RATs;
communicating, with said DUT during one of a second plurality of test intervals, at least one of a second tester data packet signal and DUT data packet signal having a second plurality of signal characteristics in accordance with a second one of said plurality of RATs;
providing, for execution by said DUT during one of a first plurality of instruction intervals, a plurality of DUT control instructions to configure said DUT to communicate said at least one of a first tester data packet signal and DUT data packet signal; and
providing, for execution by said DUT during one of a second plurality of instruction intervals, another plurality of DUT control instructions to configure said DUT to communicate said at least one of a second tester data packet signal and DUT data packet signal;
wherein
respective ones of said first plurality of test intervals and said first plurality of instruction intervals are mutually alternating,
respective ones of said second plurality of test intervals and said second plurality of instruction intervals are mutually alternating,
respective ones of said first plurality of test intervals are substantially contemporaneous with respective ones of said second plurality of instruction intervals, and
respective ones of said second plurality of test intervals are substantially contemporaneous with respective ones of said first plurality of instruction intervals.
7. The method of claim 6 , wherein:
respective ones of said first and second pluralities of test intervals are mutually alternating; and
respective ones of said first and second pluralities of instruction intervals are mutually alternating.
8. The method of claim 6 , wherein said respective ones of said first and second pluralities of test intervals are mutually exclusive.
9. The method of claim 6 , wherein said respective ones of said first and second pluralities of instruction intervals are mutually exclusive.
10. The method of claim 6 , wherein said respective ones of said first and second pluralities of instruction intervals are partially contemporaneous.
