Abstract: A system and method for testing signal reception by a data packet signal transceiver. By monitoring signals provided to and returning from a device under test (DUT), e.g., stimulus and response signals, respectively, it can be determined whether and when the DUT has received a faulty data packet or received a valid data packet in a faulty manner. When such events occur, appropriate control signals are provided for instructing the test signal reception and analysis subsystem (e.g., a vector signal analyzer) to capture and retain for analysis such faulty data packet or valid data packet received in a faulty manner. This enables the data packet reception test results to identify the number of data packets correctly received within the prescribed time interval and identify which data packet reception faults are due to reception of a faulty data packet or reception of a valid data packet in a faulty manner.
