摘要： The technology includes a method, computer medium, and system for remote testing over-the-air (OTA) audio quality using a test platform positioned at core network, the test platform comprising first and second cellular handsets and bridging logic that interconnects, controls, and bridges the first and second cellular handsets. The method includes triggering the bridging logic. The bridging logic initiates a first call over the first cellular handset to a tester, and initiates a second call over the second cellular handset to a destination, wherein the second call is initiated over-the-air. The bridging logic and the first and second cellular handsets are positioned in a location that causes routing by a cellular network of the first call over a segment under test. The bridging logic bridging audio between the first and the second calls, including relaying audio. The tester determines that the second call was established based on the relayed audio.

摘要： A test and measurement device includes a signal generator to generate a test signal, a signal analyzer to receive a response signal from an adaptive system under test (SUT), communications ports to allow reception of the response signal, and one or more processors to send a signal to the signal generator to generate a first test signal, receive a response signal from the signal analyzer, measure performance of the response signal, and report the performance to at least one of the SUT and a user workspace on the test and measurement device. A method of testing a system under test (SUT) includes generating and sending a test signal with a signal generator, receiving a response signal from the SUT at a signal analyzer, measuring performance of the response signal with respect to the test signal, and reporting the performance to at least one of the SUT and a user workspace.

摘要： A system, device and method for optimization of a radiated transmission matrix by the selecting probe antennae and applying a compensation network in the test system are described. Among other benefits, the anechoic chamber in which the DUT is disposed is comparatively small and inexpensive. The time-consuming process of inverse matrix tuning or isolation level checking that plagues known systems, device and methods of testing DUT is substantially avoided. Because of small size of shield box and probe antenna selection algorithm, low path loss and acceptable power in testing can be realized.

摘要： A calibration circuit includes a selection unit, a power detector, an analog-to-digital converter and a calibrator. The selection unit is connected to the plurality of channels, selects two channels from among the plurality of channels, provides a test signal to the selected two channels, and receives a test result signal from the selected two channels. The power detector detects power of the selected two channels. The analog-to-digital converter performs an A/D conversion on an output of the power detector. The calibrator calibrates the phases and the gains between the plurality of channels based on an output of the analog-to-digital converter. One of the plurality of channels is set as a reference channel, phases and gains of remaining channels other than the reference channel among the plurality of channels are sequentially optimized based on the reference channel, and a phase and a gain of the reference channel is optimized.
