摘要： A method of testing an electronic unit by comparing resulting signal shapes from the unit to be tested and a known functioning unit. The method includes powering off the units for testing and feeding one or more predefined signal shapes of two or more different frequencies as input signals to the known functioning unit and to the unit to be tested at corresponding test points. The method further includes measuring the resulting signal shapes from both units at corresponding measurement points and comparing at least one resulting signal shape from the known functioning unit with the corresponding resulting signal shape from the unit to be tested. The method also includes detecting a fault in the unit to be tested on the basis of an existing signal shape distortion in time axis of the resulting signal shape received from the unit to be tested.

摘要： ABSTRACT A system for inspecting or screening electrically powered device includes a signal generator inputting a preselected signal into the electrically powered device. There is also an antenna array positioned at a pre-determined distance above the electrically powered device. Apparatus collects RF energy emitted by the electrically powered device in response to input of said preselected signal. The signature of the collected RF energy is compared with an RF energy signature of a genuine part. The comparison determines one of a genuine or a counterfeit condition of the electrically powered device.

摘要： The invention relates to a method and device for testing a data link. A single-lane or multi-lane bit error tester that transmits one or more PRBS signals through the data link is augmented with a raw bit error buffer for storing bit error information for each detected error event and an error pattern analyzer. Most frequently occurring intra-lane bit error patterns, inter-lane word error patterns, and bit slip patterns are identified and their characteristics are analyzed so as to provide information indicative of root causes of the detected bit errors and bit slips.

摘要： To characterise an electrical component (1), namely a medium or high voltage transformer, electrical motor or generator, a two-step procedure is carried out. In a first step, a set of terminal configurations are applied to the terminals (p1,..., pn) of the component (1) in order to obtain data describing the linear electrical response of the component 1 to any pattern of voltages uk or currents ik applied to the terminals (p1,..., pn). Typically, such data is e.g. expressed in terms of an admittance matrix Y or impedance matrix Z or, advantageously, by the set of current and voltage vectors (ik, uk). Using this data, the linear electrical response of the component 1 under a test terminal configuration can now be calculated in a second step. This procedure allows to determine the response under any desired test terminal configuration without the need to carry out the measurement under the test terminal configuration.

摘要： Disclosed is a device for monitoring the operational state of supply and/or signal lines of an alarm system, comprising a measuring instrument which is designed and/or connected and/or can be connected so as to generate a measurement signal in accordance with the operational state in the supply and/or signal lines, and an evaluation unit that is designed to evaluate the measurement signal and output a monitoring signal on the basis of the evaluation. A controllable signal source is provided which is designed and/or connected and/or can be connected so as to inject a test signal into the supply and/or signal lines. The measurement signal encompasses the system response of the supply and/or signal lines to the test signal.

摘要： The invention relates to a method for recognising errors in a signal processing circuit elements, in particular for a measuring transducer, consisting in generating a test signal TS at a first test point TP1, in picking up a corresponding response signal AS at a second test point TP2 and in evaluating said signal in a digital unit, in comparing the individual amplitude values of the response signal AS with predefined theoretical values during the evaluation and in generating an error message if significant variations occurred.
