摘要： A method for operating a data processing system to discover the attributes of instruments in a set of instruments connected thereto is disclosed. The method causes the data processing system to determine all instruments in the set of instruments connected thereto by sending a first query on each communication link connected to the data processing system. The data processing system receives a response that identifies one of the instruments and a model identification code for that instrument. The data processing system retrieves model configuration information from an instrument catalog database attached to the data processing system based on the manufacturer's catalog information. The model configuration information includes an option that is available on the one of the instruments having the manufacturer's catalog information and a query that will cause that instrument to provide information on whether that option is installed on the one of the instruments.

摘要： A method for reconstructing uncorrectable forward error correction (FEC) data includes generating and transcoding a known bit sequence and transmitting a FEC encoded codeword that includes a payload containing the transcoded known bit sequence through a component under test. The method further includes receiving the FEC encoded codeword transmitted via the component under test and determining that the encoded contents of the FEC encoded codeword contains a number of symbol errors that exceeds a predefined threshold. The method also includes utilizing stored scramble seed bits corresponding to an immediately preceding FEC encoded codeword and the transcoded known bit sequence to generate a reconstructed codeword.

摘要： A switching converter has a first converter output for connection to a user load and a second converter output for connection to the user load. A first direct current rail power negative terminal has a first positive output and a first negative output connected to the second converter output. A second direct current rail power negative terminal has a second negative output and a second positive output connected to the first positive output. A first switch has a first positive terminal connected to the first positive output, a first negative terminal and a first control terminal. A second switch has a second positive terminal connected to the first negative terminal, a second negative terminal connected to the second negative output, and a second control terminal. A pulse width modulator has a first modulator output connected to the first control terminal, and a second modulator output connected to the second control terminal. An inductance is connected between the first converter output and the first negative terminal. A comparator controls the first pulse width modulator based on a voltage difference between a current measurement voltage that varies based on current through the inductance and a first set point voltage.

摘要： A MIMO target emulation system for testing a mmWave radar sensor having multiple radar transmitters and receivers includes a coupling probe antenna array for receiving radar signals from the radar transmitters and for sending emulated target echo signals to the radar receivers; emulator receivers for down converting and digitizing the radar signals; a processing unit that decouples the digital radar signals, retrieves target parameters corresponding to emulated targets, generates emulated target echo signals corresponding to the targets in response to the decoupled digitized radar signals using the target parameters, and pre-decoupling the emulated target echo signals; and emulator transmitters for performing digital to analog conversion of the emulated target echo signals and up converting frequencies of the analog emulated target echo signals. The emulator transmitters simultaneously send the analog emulated echo target signals to the radar sensor via the antenna array to emulate target echoes responsive to the radar signals.
