    摘要: A test equipment for testing a wireless communication device includes a wireless transceiver and a controller. The wireless transceiver transmits a first series of packets while operating in a first mode. The wireless transceiver transmits a second series of packets while operating in a second mode. The wireless transceiver receives acknowledgment packets. The controller controls the transceiver to transmit the first series of packets. The controller counts the acknowledgment packets received by the transceiver in response to transmitting each of the first series of packets. The controller controls the transceiver to transmit the second series of packets when the count exceeds a predetermined count.

    摘要: An apparatus for testing a wireless communication device includes a receiver, a capture module, and a control module. The receiver receives at least one test packet transmitted from the wireless communication device. The capture module captures at least a portion of the at least one test packet. The control module selectively controls the capture module to capture at least the portion based on a predetermined test flow. In one example, the at least one test packet is transmitted by the wireless communication device according to the predetermined test flow. In one example, control module selectively controls the capture module to capture at least the portion based on an expected calibration value associated with the at least one test packet. In one example, the control module selectively controls the capture module to capture at least the portion based on a predetermined value of interest.

    摘要: The saturation compensating analog to digital converter has converter circuitry receiving an analog signal and outputting converted data. The converted data from the converter circuitry is processed and filtered to provide a digital data output. The digital data output is received into shift register circuitry before being transmitted for later-stage processing. When the converter circuitry is operating close to a saturated condition, a saturation detector generates a saturation signal. The saturation signal is received at a variable gain circuit which adjusts the gain of the input signal to the converter circuitry. The shift register circuitry also receives the saturation signal and provides an upshift of the digital data to compensate for the associated reduction in input gain provided by the variable gain circuit. In operation, the variable gain circuit is initially set to its maximum output, thus providing the maximum possible input signal to the converter. If a near-saturation conditional is detected, the variable gain circuit is stepped down, and the shift register circuitry provides an associated one bit step up. Such saturation compensation is continued to enable the converter circuitry to operate without saturating.

    摘要: An apparatus and method of operating automated test equipment (ATE) in a networked environment of multiple external test controllers. The system resources responsible for coordinating the shared uses of the ATE by the multiple external test controllers are centralized within the ATE. As a result, programming of the respective test controllers is simplified since the test controllers no longer need be responsible for communicating among themselves to coordinate or otherwise determine how and when access to the ATE is granted to any particular test controller.

    摘要: Execution of a block test “retry” in a test environment with each block in the test sequence sent after the tester has determined that the previous block of data packets has met one or more prescribed test criterion. If a block sent by the DUT has not met the test criterion, a retry sequence is initiated to re-test the block. In another embodiment, a block test “retry” is executed where each block in the test sequence is sent and analysis of previously sent blocks is done in parallel with the sending of a subsequent block. If a previous block has not met the test criterion, a retry sequence is initiated whereby the tester and DUT step back to the block that failed to meet the test criterion and retry that block. If the retry meets test criterion, testing continues by resuming with the next untested block in the sequence.
