Method for testing a radio frequency (RF) data packet signal transceiver with multiple transmitters and receivers capable of concurrent operations
View Patent ↗Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) with multiple RF signal transmitters and RF signal receivers capable of concurrent operations. Multiple successions of test data packets from a tester to respective RF signal receivers of the DUT and multiple successions of responsive DUT data packets from respective RF signal transmitters of the DUT to the tester are conveyed such that multiple RF signal transmissions, multiple RF signal receptions, or RF signal transmission and reception are performed at least partially concurrently.
1. A method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) with at least first and second RF signal transmitters and first and second RF signal receivers capable of concurrent operations, comprising:
transmitting a first RF test data packet signal including a succession of a first plurality of test data packets;
receiving, from said first RF signal transmitter, a first RF DUT data packet signal responsive to one or more portions of said first RF test data packet signal in which said first RF DUT data packet signal includes a succession of a first plurality of DUT data packets, wherein each of said succession of said first plurality of DUT data packets is associated with each of said succession of said first plurality of test data packets;
transmitting a second RF test data packet signal including a succession of a second plurality of test data packets; and
receiving, from said second RF signal transmitter, a second RF DUT data packet signal responsive to one or more portions of said second RF test data packet signal in which said second RF DUT data packet signal includes a succession of a second plurality of DUT data packets, wherein each of said succession of said second plurality of DUT data packets is associated with each of said succession of said second plurality of test data packets;
wherein
each of said succession of said first plurality of DUT data packets is received at least partially concurrently with transmission of a respective one of said succession of said second plurality of test data packets, and
each of said succession of said second plurality of DUT data packets is received at least partially concurrently with transmission of a respective one of said succession of said first plurality of test data packets.
2. The method of claim 1 , wherein each of said succession of said first plurality of test data packets has a duration equal to each of said succession of said second plurality of test data packets.
3. The method of claim 1 , wherein each of said succession of said first plurality of test data packets has a duration less than each of said succession of said second plurality of test data packets.
4. The method of claim 1 , wherein each of said succession of said first plurality of test data packets is transmitted at least partially concurrently with transmission of a respective one of said succession of said second plurality of test data packets.
5. The method of claim 1 , wherein respective ones of said succession of said first and second pluralities of DUT data packets are received during mutually exclusive time intervals.
6. A method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) with at least first and second RF signal transmitters and first and second RF signal receivers capable of concurrent operations, comprising:
transmitting a first RF test data packet signal including a succession of a first plurality of test data packets;
receiving, from said first RF signal transmitter, a first RF DUT data packet signal responsive to one or more portions of said first RF test data packet signal in which said first RF DUT data packet signal includes a succession of a first plurality of DUT data packets, wherein each of said succession of said first plurality of DUT data packets is associated with each of said succession of said first plurality of test data packets;
transmitting a second RF test data packet signal including a succession of a second plurality of test data packets; and
receiving, from said second RF signal transmitter, a second RF DUT data packet signal responsive to one or more portions of said second RF test data packet signal in which said second RF DUT data packet signal includes a succession of a second plurality of DUT data packets, wherein each of said succession of said second plurality of DUT data packets is associated with each of said succession of said second plurality of test data packets;
wherein
each of said succession of said first plurality of DUT data packets is received at least partially concurrently with transmission of a respective one of said succession of said second plurality of test data packets, and
said succession of said first and second pluralities of DUT data packets are received during mutually exclusive time intervals.
7. The method of claim 6 , wherein each of said succession of said first plurality of test data packets has a first duration, each of said succession of said second plurality of test data packets has a second duration, and said first and second durations are unequal.
8. The method of claim 6 , wherein each of said succession of said first plurality of test data packets is transmitted at least partially concurrently with transmission of a respective one of said succession of said second plurality of test data packets.
9. The method of claim 6 , wherein said succession of said first and second pluralities of test data packets are transmitted during mutually exclusive time intervals.
