Abstract

Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of multiple available signal channels. Data packets exchanged between a tester and DUT as a normal part of a communication link initiation sequence are exchanged in such a manner that the tester transmits via all available channels simultaneously, thereby ensuring that a properly working DUT will always transmit in response. For example, in the case of a Bluetooth low energy transceiver, advertisement, scan request and scan response data packets can be used in such manner.

First claim

What is claimed is:

1. A method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of a plurality of signal channels, comprising:
receiving, with a tester via one of said plurality of signal channels, a link initiation data packet from said DUT;
transmitting, with said tester via each one of said plurality of signal channels simultaneously, a tester response data packet responsive to said link initiation data packet; and
receiving, with said tester via said one of said plurality of signal channels, a DUT response data packet responsive to said tester response data packet.

2. The method of claim 1 , wherein said DUT response data packet is responsive to said tester response data packet transmitted with said tester via said one of said plurality of signal channels.

3. The method of claim 1 , wherein:
said DUT comprises a Bluetooth low energy device;
said link initiation data packet comprises an advertisement data packet;
said tester response data packet comprises a scan request data packet; and
said DUT response data packet comprises a scan response data packet.

4. The method of claim 1 , further comprising:
receiving, with said tester via another one of said plurality of signal channels, another link initiation data packet from said DUT;
transmitting, with said tester via each one of said plurality of signal channels simultaneously, another tester response data packet responsive to said another link initiation data packet; and
receiving, with said tester via said another one of said plurality of signal channels, another DUT response data packet responsive to said another tester response data packet.

5. The method of claim 4 , wherein said another DUT response data packet is responsive to said another tester response data packet transmitted with said tester via said another one of said plurality of signal channels.

6. The method of claim 1 , wherein said DUT response data packet includes a plurality of signal characteristics, and further comprising analyzing, with said tester, at least one of said plurality of signal characteristics.

7. A method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of a plurality of signal channels, comprising:
transmitting, with said DUT via one of said plurality of signal channels, a link initiation data packet;
receiving, with said DUT via each one of said plurality of signal channels simultaneously, a tester response data packet responsive to said link initiation data packet; and
transmitting, with said DUT via said one of said plurality of signal channels, a DUT response data packet responsive to said tester response data packet.

8. The method of claim 7 , wherein said DUT response data packet is responsive to said tester response data packet received with said DUT via said one of said plurality of signal channels.

9. The method of claim 7 , wherein:
said DUT comprises a Bluetooth low energy device;
said link initiation data packet comprises an advertisement data packet;
said tester response data packet comprises a scan request data packet; and
said DUT response data packet comprises a scan response data packet.

10. The method of claim 7 , further comprising:
transmitting, with said DUT via another one of said plurality of signal channels, another link initiation data packet;
receiving, with said DUT via each one of said plurality of signal channels simultaneously, another tester response data packet responsive to said another link initiation data packet; and
transmitting, with said DUT via said another one of said plurality of signal channels, another DUT response data packet responsive to said another tester response data packet.

11. The method of claim 10 , wherein said another DUT response data packet is responsive to said another tester response data packet transmitted with said tester via said another one of said plurality of signal channels.

12. A method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of a plurality of signal channels, comprising:
transmitting, with said DUT via one of said plurality of signal channels, a link initiation data packet;
receiving, with a tester, said link initiation data packet and in response thereto transmitting, via each one of said plurality of signal channels simultaneously, a tester response data packet;
receiving, with said DUT via each one of said plurality of signal channels simultaneously, said tester response data packet and in response thereto transmitting, via said one of said plurality of signal channels, a DUT response data packet; and
receiving, with said tester via said one of said plurality of signal channels, said DUT response data packet.

13. The method of claim 12 , wherein said DUT response data packet is responsive to said tester response data packet transmitted with said tester via said one of said plurality of signal channels.

14. The method of claim 12 , wherein:
said DUT comprises a Bluetooth low energy device;
said link initiation data packet comprises an advertisement data packet;
said tester response data packet comprises a scan request data packet; and
said DUT response data packet comprises a scan response data packet.

15. The method of claim 12 , further comprising:
transmitting, with said DUT via another one of said plurality of signal channels, another link initiation data packet;
receiving, with said tester, said another link initiation data packet and in response thereto transmitting, via each one of said plurality of signal channels simultaneously, another tester response data packet;
receiving, with said DUT via each one of said plurality of signal channels simultaneously, said another tester response data packet and in response thereto transmitting, via said another one of said plurality of signal channels, another DUT response data packet; and
receiving, with said tester via said another one of said plurality of signal channels, said another DUT response data packet.

16. The method of claim 15 , wherein said another DUT response data packet is responsive to said another tester response data packet transmitted with said tester via said another one of said plurality of signal channels.

17. The method of claim 12 , wherein said DUT response data packet includes a plurality of signal characteristics, and further comprising analyzing, with said tester, at least one of said plurality of signal characteristics.
