System and method for performing over-the-air testing of device under test

A test system for performing over-the-air (OTA) testing of a device under test (DUT), the system comprising:

• (1) a shield box containing at least a coupling antenna for communicating radio frequency (RF) signals OTA with the DUT when located within the shield box;
• and
• (2) a radio frequency (RF) module electrically connected to the antenna in the shield box, the RF module comprising:
• a transceiver for sending and receiving RF signals to and from the antenna in the shield box via an OTA connection with the DUT, the RF signals including advertising information broadcast by the DUT over at least one advertising channel, universally unique identifier (UUID) requests sent to the DUT over at least one data channel of the OTA connection, and UUID responses received from the DUT in response to at least some of the UUID requests over the at least one data channel of the OTA connection;
• a main controller programmed to control operations of the RF module, including:
• establishing the OTA connection between the transceiver and the DUT via the antenna in the shield box based on the advertising information received over the at least one advertising channel, while the DUT is in signaling mode;
• and
• a wireless personal area network (WPAN) processor programmed to execute a receiver sensitivity measurement of a receiver in the DUT, corresponding to BLE 5.0 specification, including:
• causing the transceiver to send the UUID requests at different transmit powers to the DUT over the at least one data channel of the OTA connection,
• receiving UUID responses from the DUT over the at least one data channel of the OTA connection in response to at least some of the UIDD requests, and
• determining a packet error rate (PER) of the UUID requests based on a ratio of a number of received UUID responses and a number of sent UUID requests, the determined PER indicating sensitivity of a receiver in the DUT.

A method of performing over-the-air (OTA) testing of a device under test (DUT), the method comprising:

• establishing an OTA connection with the DUT, while the DUT is in signaling mode, the OTA connection comprising a fixed channel of the DUT;
• sending status requests at different transmit powers to the DUT over the fixed channel of the OTA connection, the status request being sent to a unique identifier associated with the DUT;
• receiving status responses from the DUT over the fixed channel of the OTA connection in response to at least some of the status requests;
• and
• determining a packet error rate (PER) for the received status responses from the DUT based on a ratio of a number of received status responses and a number of sent status requests, the determined PER indicating sensitivity of a receiver in the DUT.
