Method for testing a low power radio frequency (RF) data packet signal transceiver
View Patent ↗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 with varied signal power via all available channels simultaneously, thereby ensuring that a properly working DUT will transmit in response to reception of tester data packets having sufficient signal power. 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.
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 a first one of said plurality of signal channels, a first link initiation data packet from said DUT;
transmitting, with said tester and a first signal power via each one of said plurality of signal channels simultaneously, a first tester response data packet responsive to said first link initiation data packet;
receiving, with a tester via a second one of said plurality of signal channels, a second link initiation data packet from said DUT;
transmitting, with said tester and a second signal power via each one of said plurality of signal channels simultaneously, a second tester response data packet responsive to said second link initiation data packet, wherein said first and second signal powers are unequal; and
receiving, with said tester,
via said first one of said plurality of signal channels, a DUT response data packet responsive to said first tester response data packet, or
via said second one of said plurality of signal channels, a DUT response data packet responsive to said second tester response data packet.
2. The method of claim 1 , wherein said first signal power is greater than said second signal power.
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 , 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.
5. 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 a first one of said plurality of signal channels, a first link initiation data packet;
receiving, with said DUT and a first signal power via each one of said plurality of signal channels simultaneously, a first tester response data packet responsive to said first link initiation data packet;
transmitting, with said DUT via a second one of said plurality of signal channels, a second link initiation data packet;
receiving, with said DUT and a second signal power via each one of said plurality of signal channels simultaneously, a second tester response data packet responsive to said second link initiation data packet, wherein said first and second signal powers are unequal; and
transmitting, with said DUT,
via said first one of said plurality of signal channels, a DUT response data packet responsive to said first tester response data packet, or
via said second one of said plurality of signal channels, a DUT response data packet responsive to said second tester response data packet.
6. The method of claim 5 , wherein said first signal power is greater than said second signal power.
7. The method of claim 5 , 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.
8. 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 a first one of said plurality of signal channels, a first link initiation data packet;
receiving, with a tester, said first link initiation data packet and in response thereto transmitting, with a first signal power via each one of said plurality of signal channels simultaneously, a first tester response data packet;
transmitting, with said DUT via a second one of said plurality of signal channels, a second link initiation data packet;
receiving, with a tester, said second link initiation data packet and in response thereto transmitting, with a second signal power via each one of said plurality of signal channels simultaneously, a second tester response data packet, wherein said first and second signal powers are unequal; and
receiving, with said DUT via each one of said plurality of signal channels simultaneously,
said first tester response data packet and in response thereto transmitting via said first one of said plurality of signal channels, a DUT response data packet, or
said second tester response data packet and in response thereto transmitting via said second one of said plurality of signal channels, a DUT response data packet.
9. The method of claim 8 , wherein said first signal power is greater than said second signal power.
10. The method of claim 8 , 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.
11. The method of claim 8 , 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.
