摘要： An example waveguide connector is for making a blind-mate electrical connection between a first waveguide and a second waveguide. The waveguide connector includes a male part connected to the first waveguide, where the first waveguide includes a first conductive channel, and a female part connected to the second waveguide, where the second waveguide includes a second conductive channel. The female part includes a receptacle into which the male part slides to create the blind-mate electrical connection between the first conductive channel and the second conductive channel. A self-alignment feature is on at least one of the male part or the female part. The self-alignment feature is configured to guide the male part into the receptacle while correcting for misalignment of the male part and the female part.

摘要： An example system for testing a device under test (DUT) includes one or more processing devices configured to receive first data from the DUT over a communication channel, and to analyze the first data to identify an error associated with the communication channel; and a power supply controller configured to receive second data based on a power disturbance from the DUT, and to compare the first data and the second data to determine if there is a correlation between the power disturbance and the error.

摘要： Example techniques may be implemented as a method, a system or more non-transitory machine-readable media storing instructions that are executable by one or more processing devices, Operations performed by the example techniques include obtaining data representing results of tests executed by one or more test instruments on an initial set of devices under test (DUTs) in a test system; and using the data to train a machine learning model. The machine learning model is for predicting which of the tests will produce failing results for a different set of DUTs. DUTs in the different set have one or more features in common with DUTs in the initial set.

摘要： An example test system includes test sites for testing devices under test (DUTs), where the test sites include a test site configured to hold a DUT for testing. The test system includes a thermal control system to control a temperature of the DUT separately from control over temperatures of other DUTs in other test sites. The thermal control system includes a thermoelectric cooler (TEC) and a structure that is thermally conductive. The TEC is in thermal communication with the DUT to control the temperature of the DUT by transferring heat between the DUT and the structure.

摘要： An example system includes a first circuit board having first conductive traces, where a first conductive trace is for conducting an alternating current (AC) digital signal having an edge; a second circuit board having second conductive traces, where a second conductive trace is within a predefined distance of the first conductive trace to produce a contactless coupling with the first conductive trace, and where the contactless coupling enables electrical energy on the first conductive trace to manifest on the second conductive trace as a transient response that is based on the edge; and circuitry to reconstruct the edge based on the transient response from the second conductive trace.

摘要： Circuitry and methods of operating the same to strobe a DQ signal with a gated DQS signal are described. Some aspects are directed to a gating scheme to selectively pass a received strobe signal such as a DQS strobe signal based on a state of a drive enable (DE) signal in a drive circuit in the ATE, such that edges generated by the drive circuit are prevented from mistakenly strobing a received data signal such as a DQ signal.

摘要： A method and computing system comprising identifying a plurality of robot configurations for each inspection point of a plurality of inspection points of a problem. A graph may be generated with each feasible robot configuration as a node on the graph. A distance may be calculated between a pair of feasible robot configurations. A shortest complete path connecting each node on the graph may be obtained based upon, at least in part, the distance between the pair of feasible robot configurations.

摘要： An example printed circuit board (PCB) includes a substrate having layers of a dielectric material, where the layers of dielectric material include a first layer and a second layer; a conductive trace that is between the first layer and the second layer and that is parallel to the first layer and the second layer along at least part of a length of the conductive trace; and a conductive via that extends at least part-way through the layers of dielectric material and that connects electrically to the conductive trace, where the conductive via is configured also to connect electrically to a signal input to receive or to transmit a signal that has a center frequency span.
