Problems solved by technology
However, querying the DUT is inefficient due to the additional test time required to accommodate the exchange of query and reply packets
[0008] Additionally, the development software for manufacturing test is significantly complicated by the fact that DUT calibration is often implemented differently between chipset manufacturers and from manufacturer's chipset to chipset
For example, as noted, calibration for receive (RX) signal operation is often particularly time-consuming due to the need to interrogate the DUT for its receiver operating status and / or performance

System and method for testing transmission and reception performance of a data packet signal transceiver device under test (DUT). Data packet signals transmitted by a tester with a tester transmit output power (TTOP) contain trigger frames that include data corresponding to a reported tester transmit power (RTTP) of the data packet signals, and a desired received signal strength (TRSS) of DUT data packet signals to be received by the tester. Based on received signal strength of the tester data packet signals reported by the DUT (DRSS), responsive DUT data packet signals having a DUT transmit output power of RTTP-DRSS+TRSS. Successive repetitions of such tester and DUT data packet signals for multiple combinations of values of the TTOP, RTTP and DRSS enable testing transmission and reception performance of the DUT, including determining minimum and maximum DUT transmission power levels, with minimal signal interactions between tester and DUT.
Description
Background technique [0001] The present invention relates to testing a data packet signal transceiver device under test (DUT), and in particular, to testing the transmit and / or receive performance of the DUT with minimal required signal interaction between the tester and the DUT. [0002] Many of today's electronic devices use wireless signal technology for connection and communication purposes. Because wireless devices emit and receive electromagnetic energy, and because the signal frequencies and power spectral densities of two or more wireless devices have the potential to interfere with each other's operation, these devices, as well as their wireless signal technology, must comply with various wireless signal technology standards specification. [0003] In designing such wireless devices, engineers take extreme care to ensure that such devices will meet or exceed the stated standard specifications for each of the wireless signal technologies involved. In addition, when t...
