System and method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) to enable use of measured packet error rate (PER) to determine transmit signal quality and thereby estimate error vector magnitude (EVM) of the DUT. By using a reference RF data packet signal transceiver having device characteristics and capabilities similar to the DUT including a low noise figure, in place of a formal test instrument with a significantly higher noise figure, significantly lower power DUT transmit signals can be tested, since the additional SNR is not required to determine transmit signal quality, thereby enabling reliable testing of transmit signal quality of the lower power signals from the DUTs. <u>With a calibrated reference RF data packet signal receiver, a reduction in sensitivity as compared to the calibrated sensitivity indicates a reduced transmit signal quality of the received packet.</u> |
