    摘要: A test and measurement instrument includes one or more ports including at least one test port configured to couple to one or more devices under test, a user interface to receive one or more user inputs, an acquisition memory to store waveform data acquired from the one or more devices under test, one or more processors configured to execute code that causes the one or more processors to: receive an input through the user interface; determine one or more requested data types based on the input; transform the waveform data into compressed data containing only data elements corresponding to the one or more requested data types; and transmit the compressed data to a client. A method of providing usage-aware compressed data from a test and measurement instrument includes acquiring waveform data from one or more devices under test, receiving a user input through a user interface, determining one or more requested data types based on the user input, transforming the waveform data into compressed data containing only data elements corresponding to the one or more requested data types, and transmitting the compressed data to a client.

    摘要: A sensor device is provided for testing electrical connections in a DUT using contactless fault detection. The sensor device includes main traces for conducting an RF signal supplied by a signal source; at least one inductor connected to at least one of the main traces; and a slit formed between opposing conductor portions at a tip of the sensor device for sensing open circuits and/or short circuits in portions of the DUT located in a sensing region below the slit, the tip being at an end of the sensor device opposite ends of the main traces connected to the signal source. An electric field, generated by the sensor device in response to the RF signal, substantially concentrates in the slit, enhancing the sensing of the open and/or the short circuits during the contactless fault detection.

    摘要: A programmable semiconductor device contains a wireless communication block (“WCB”) capable of facilitating wirelessly field programmable gate array (“FPGA”) programming download as well as functional logic implementation. In one aspect, WCB detects an FPGA access request for initiating an FPGA reconfiguration from a remote system via a wireless communications network. Upon receiving a configuration bitstream for programming the FPGA via the wireless communications network, the configuration bitstream is forwarded from WCB to a configuration download block (“CDB”) for initiating a configuration process. CDB subsequently programs at least a portion of configurable logic blocks (“LBs”) in FPGA in response to the configuration bitstream.

    摘要: An over-the-air test system is described that is used for testing a device under test in a wireless communication environment. The test system comprises at least one measurement antenna connected with a signal processing unit configured to generate a signal or to analyze a signal. The test system further comprises a reflector configured to reflect electromagnetic signals, the reflector being positioned in a signal path established between the device under test and the measurement antenna such that the signals are reflected by the reflector. The measurement antenna has a radiation pattern with a main lobe, the measurement antenna being configured to adjust the direction of the main lobe with respect to the reflector in order to simulate different impinging angles of the signals. Further, a method for testing a device under test is described.
